172	1. Introduction
173
174	This document describes a set of XSLT transformations that can be
175	used to transform RFC2629-compliant XML (see [RFC2629]) to various
176	output formats, such as HTML and PDF. The main topics are
177
178	o compliance to the xml2rfc XML element set (Section 2),
179
180	o support for xml2rfc processing instructions (Section 3),
181
182	o the names of anchor elements generated in HTML and PDF output
183	(Section 4),
184
185	o various XSLT engines that can be used (Section 5),
186
187	o outputting HTML (Section 6) and XHTML (Section 7),
188
189	o outputting CHM (Compiled Microsoft Help, Section 8),
190
191	o outputting PDF (Section 9),
192
193	o extensions to the xml2rfc vocabulary (Section 11).
194
195	o various utilities (Section 12).
196
197	The full distribution is available at
198	<http://greenbytes.de/tech/webdav/rfc2629xslt.zip>.

228	2. Supported RFC2629 elements
229
230	"rfc2629.xslt" supports both all RFC2629 grammar elements and the
231	extensions implemented in xml2rfc 1.33.
232
233	2.1. Extension elements
234
235	"rfc2629.xslt" supports two kind of extension elements, using
236	different XML namespaces.
237
238	The first set contains (hopefully) generally useful extensions, see
239	Section 11.
240
241	The second set is used for change and issue tracking and currently is
242	not documented here. Please email the author in case you're
243	interested in using these extensions.

284	3. Processing Instructions
285
286	All PIs can be set as XSLT parameter as well, overriding any value
287	that is found in the source file to be transformed.
288
289	Using processing instructions:
290
291	<?rfc toc="yes"?>
292	<?rfc-ext support-rfc2731="no"?>
293
294	Using XSLT parameters (Saxon):
295
296	java -cp saxon.jar com.icl.saxon.StyleSheet source.xml rfc2629.xslt \
297	xml2rfc-toc=yes xml2rfc-ext-support-rfc2731=no > result.html
298
299	Using XSLT parameters (xsltproc):
300
301	xsltproc --param xml2rfc-toc '"yes"' \
302	--param xml2rfc-ext-support-rfc2731 '"no"' \
303	rfc2629.xslt source.xml > result.html
304
305	(note the required quoting of string parameters)

676	4. Anchors
677
678	The transformation automatically generates anchors that are supposed
679	to be stable and predictable and that can be used to identify
680	specific parts of the document. Anchors are generated both in HTML
681	and XSL-FO content (but the latter will only be used for PDF output
682	when the XSL-FO engine supports producing PDF anchors).

788	5. Supported XSLT engines
789
790	The transformation requires a non-standard extension function (see
791	exsl:node-set [1]) which is however widely available. XSLT
792	processors that do not support this extension (or a functional
793	equivalent) currently are not supported.
794
795	5.1. Standalone Engines
796
797	The following XSLT engines are believed to work well:
798
799	o Windows: MSXML3 and MSXML4 (<http://msdn.microsoft.com/xml>;
800	command line processor "msxsl" is available from Microsoft
801	Download Center [2])
802
803	o Java: Saxon (<http://saxon.sourceforge.net/>)
804
805	o Java: Xalan (<http://xml.apache.org/xalan-j/>)
806
807	o C/C++: xsltproc (libxslt) (<http://xmlsoft.org/XSLT/>, make sure
808	that you have a current version)
809
810	5.2. In-Browser Engines
811
812	The following browsers seem to work fine:
813
814	o Internet Explorer 5.5 (Windows version, if MSXML3 is installed)
815
816	o Internet Explorer 6 and newer
817
818	o Firefox 3.0 and newer
819
820
821	* Be aware that XSLT execution can be suppressed using
822	NoScript [3]
823
824	* Firefox does not load external DTDs nor external entities, see
825	Mozilla Bug 22942 [4], thus entities like   need to be
826	declared in the internal subset (Appendix C.1)
827
828	* There seems to be a new problem in Firefox 4 where it
829	occasionally does the initial rendering with the wrong width
830	(people who can reproduce this problem please comment on
831	<https://bugzilla.mozilla.org/show_bug.cgi?id=640390>.
832
833	o Safari 3 (starting with version 3.0.4)

839	Reschke [Page 15]
840

842
843
844	o Google Chrome
845
846	o Opera (starting with version 10)
847
848	The following browsers are known not to work properly:
849
850	o Firefox 1./2.: (missing extension function - see change request
851	at Mozilla BugZilla 193678 [5])
852
853	o Opera 9.21: execution fails, potentially to a somewhat complex
854	XPath expression (reported to Opera as bug 245725).
855
856	o Opera 9.5 and 9.6: transformation appears to work, but CSS isn't
857	getting applied (reported to Opera as bug 337388 on 2008-06-12).
858
859	o Safari 2.* supports client-side XSLT as of MacOS X 10.4, but
860	misses required extension functions. A problem with stylesheets
861	producing non-ASCII output (such as NBSP characters) has been
862	fixed as of OSX 10.4.4. Both problems have been reported through
863	Apple's bug tracking system, see <http://drakken.dbc.mtview.ca.us/
864	pipermail/xml2rfc/2005-May/002073.html> and
865	<http://bugs.webkit.org/show_bug.cgi?id=4079>.

900	6. Transforming to HTML
901
902	Transformation to HTML can be done inside the browser if it supports
903	XSLT. To enable this, add the following processing instruction to
904	the start of the source file:
905
906	<?xml-stylesheet type='text/xsl' href='rfc2629.xslt' ?>
907
908	(and ensure that "rfc2629.xslt" is present).
909
910	6.1. HTML compliance
911
912	The transformation result is supposed to conform to the HTML 4.01
913	strict DTD [HTML]. This can be checked using the W3C's online
914	validator at <http://validator.w3.org>.
915
916	6.2. Standard HTML LINK elements
917
918	LINK elements exist since HTML 2.0. They can be used to embed
919	content-independant links inside the document. Unfortunately, only
920	few user agents support this element. Firefox users may want to
921	check the Link Widgets [6] extension.
922
923	The following LINK elements are produced:
924
925	+-----------+-------------------------------------------------------+
926	\| LINK type \| description \|
927	+-----------+-------------------------------------------------------+
928	\| alternate \| for RFCs, a link to the authorative ASCII version on \|
929	\| \| the IETF web site \|
930	\| \| \|
931	\| appendic \| pointer to all top-level appendics \|
932	\| \| \|
933	\| author \| pointer to "authors" section \|
934	\| \| \|
935	\| chapter \| pointer to all top-level sections \|
936	\| \| \|
937	\| contents \| pointer to table of contents \|
938	\| \| \|
939	\| copyright \| pointer to copyright statement \|
940	\| \| \|
941	\| index \| pointer to index \|
942	+-----------+-------------------------------------------------------+
943
944	The figure below shows how Mozilla Firefox 1.0 displays the Site
945	Navigation Bar for rfc2396.xml.

955
956	6.3. Standard HTML metadata
957
958	The following standard HTML META elements are produced:
959
960	+-----------+-------------------------------------------------+
961	\| META name \| description \|
962	+-----------+-------------------------------------------------+
963	\| generator \| from XSLT engine version and stylesheet version \|
964	\| \| \|
965	\| keywords \| from keyword elements in front section \|
966	+-----------+-------------------------------------------------+
967
968	6.4. Dublin Core (RFC2731) metadata
969
970	Unless turned off using the "rfc-ext support-rfc2731" processing
971	instruction, the transformation will generate metadata according to
972	[RFC2731] and [DC-HTML].
973
974	The following DCMI properties are produced:
975
976	+-------------------------+-----------------------------------------+
977	\| META name \| description \|
978	+-------------------------+-----------------------------------------+
979	\| DC.Creator \| from author information in front \|
980	\| \| section \|
981	\| \| \|
982	\| DC.Date.Issued \| from date information in front section \|
983	\| \| \|
984	\| DC.Description.Abstract \| from abstract \|
985	\| \| \|
986	\| DC.Identifier \| document URN [RFC2648] from "docName" \|
987	\| \| attribute \|
988	\| \| \|
989	\| DC.isPartOf \| RFC ISSN (for RFCs) \|
990	\| \| \|

1012	7. Transforming to XHTML
1013
1014	Transforming to XHTML requires slightly different XSLT output options
1015	and is implemented by the derived transformation script
1016	"rfc2629toXHTML.xslt".
1017
1018	Note: Microsoft Internet Explorer does _not_ support XHTML.
1019	Therefore it usually makes more sense to generate plain old HTML.

1068	8. Transforming to CHM (Microsoft Compiled Help)
1069
1070	To generate a CHM file using Microsoft's HTML Help Compiler (hhc),
1071	three files are required in addition to the HTML file.
1072
1073	1. hhc - table of contents file (HTML)
1074
1075	2. hhk - index file (HTML)
1076
1077	3. hhp - project file (plain text)
1078
1079	The three files are generated with three specific transformations,
1080	each requiring the additional XSLT parameter "basename" to specify
1081	the filename prefix.
1082
1083	Example:
1084
1085	saxon rfc2616.xml rfc2629toHhp.xslt basename=rfc2616 > rfc2616.hhp
1086	saxon rfc2616.xml rfc2629toHhc.xslt basename=rfc2616 > rfc2616.hhc
1087	saxon rfc2616.xml rfc2629toHhk.xslt basename=rfc2616 > rfc2616.hhk

1124	9. Transforming to PDF
1125
1126	9.1. Via XSL-FO
1127
1128	Transformation to XSL-FO [XSL-FO] format is available through
1129	"rfc2629toFO.xslt" (which includes "rfc2629.xslt", so keep both in
1130	the same folder).
1131
1132	Compared to HTML user agents, XSL-FO engines unfortunately either
1133	come as open source (for instance, Apache FOP) or feature-complete
1134	(for instance, AntennaHouse XSL Formatter), but not both at the same
1135	time.
1136
1137	As Apache FOP needs special workarounds (index generation), and some
1138	popular extensions aren't standardized yet, the translation produces
1139	a generic output (hopefully) conforming to [XSL-FO]. Specific
1140	backends ("xsl11toFop.xslt", "xsl11toXep.xslt", "xsl11toAn.xslt")
1141	then provide post-processing for the individual processors.
1142
1143	Note: the output is currently targeted at Apache FOP 1.0.

1193	9.2. Via X(HTML)
1194
1195	PDF output can also be produced directly from (X)HTML. One simple
1196	approach is to rely on the browser's printing function, and to use a
1197	printer driver that produces PDF. Depending on the brower's CSS
1198	capabilities, the output will behave properly with respect to table
1199	breaks etc.
1200
1201	An alternative is PrinceXML (see <http://www.princexml.com/>), which
1202	can produce PDF directly from (X)HTML input, based on the CSS
1203	printing information.
1204
1205	For instance, PDF output with text justification turned on can be
1206	produced with:
1207
1208	saxon input.xml rfc2629toXHTML.xslt xml2rfc-ext-justification=print \
1209	> output.xhtml
1210	prince output.xhtml output.pdf

1236	10. Transforming to ePub
1237
1238	Experimental transformation to ePub format is available through a set
1239	of stylesheets, and the Unix Shell script "mkepub.sh" (which requires
1240	that "zip" and either "saxon" or "xsltproc" are installed).
1241
1242	For instance, an epub version of rfc2616.xml can be generated like
1243	this:
1244
1245	mkepub.sh rfc2616.xml

1292	11. Generic Extensions
1293
1294	This section documents extensions implemented in "rfc2629.xslt",
1295	using the extension namespace "http://purl.org/net/xml2rfc/ext".
1296
1297	11.1. <abnf-char-sequence> element
1298
1299	Converts the contained quoted string into a hex-encoded character
1300	sequence, for use in case-sensitive ABNF productions.
1301
1302	For instance, "<x:abnf-char-sequence>"HTTP"</x:abnf-char-sequence>"
1303	gets converted to "%x48.54.54.50".
1304
1305	11.2. <anchor-alias> element
1306
1307	Using its "value" attribute, this element allows the definition of an
1308	internal link target alias for the enclosing element. This alias can
1309	then be used with the <ref> element for intra-document references.
1310
1311	Note that the anchor alias is not subject to the naming constraints
1312	that apply to anchor elements (which are XML names).
1313
1314	11.3. <bcp14> element
1315
1316	This element marks the content as being one of the normative keywords
1317	defined in [RFC2119].

1373	11.4. <bb> element
1374
1375	Marking up a string as <bb> indicates that it represents the bottom
1376	line of a box drawing, replacing the "+" and "-" characters
1377	accordingly.
1378
1379	11.5. <bc> element
1380
1381	Marking up a string as <bc> indicates that it represents a center
1382	line of a box drawing, replacing the "\|" character accordingly.
1383
1384	11.6. <blockquote> element
1385
1386	This element is like the "blockquote" element in [HTML] (note this is
1387	a block-level element!). It should contain one or more <t> child
1388	elements.
1389
1390	11.7. <boilerplate> element
1391
1392	Can be used to include boilerplate (status, copyright, ...) into the
1393	front or back section. <section> elements within <x:boilerplate>
1394	appear as unnumbered sections in the output.

1404	_This element currently can not be "down-translated" for use in
1405	xml2rfc!_
1406
1407	11.8. <bt> element
1408
1409	Marking up a string as <bt> indicates that it represents the top line
1410	of a box drawing, replacing the "+" and "-" characters accordingly.
1411
1412	11.9. <dfn> element
1413
1414	This element is like the "dfn" element in [HTML].
1415
1416	11.10. <h> element
1417
1418	This element is like the "h" element in [XHTML2].
1419
1420	11.11. <highlight> element
1421
1422	Used to highlight text passages, currently only allowed in <artwork>.
1423
1424	Note: this is stripped when generating input for xml2rfc, so please
1425	use with care.
1426
1427	11.12. <length-of> element
1428
1429	This element can be used to insert the length of another formatted
1430	section (in decimal).
1431
1432	Example: computing the Content-Length header value
1433
1434	<artwork>
1435	...
1436	Content-Length: <x:length-of target="req"/>
1437
1438	<x:span anchor="req">123456789
1439	<x:span><artwork/>
1440
1441	The lenght computation counts line ends as two characters (CRLF).
1442
1443	Note that indentation characters in artwork _will_ be counted. The
1444	"indented" attribute allows to specify the amount of indentation to
1445	be substracted from the computed length.
1446
1447	11.13. <link> element
1448
1449	This element can be added as a top-level child element below <rfc> to
1450	indicate additional link information. It's currently used only when
1451	generating HTML output, in which case an HTML <link> element with
1452

1456
1457	Documentation RFC2629 through XSLT March 2011
1458
1459
1460	identical attributes gets generated.
1461
1462	Example: generating HTML link element
1463
1464	<x:link xmlns="http://purl.org/net/xml2rfc/ext"
1465	rel="Bookmark"
1466	title="IETF WEBDAV Working Group"
1467	href="http://ftp.ics.uci.edu/pub/ietf/webdav/"/>
1468
1469	11.14. <lt> element
1470
1471	Used for grouping multiple <t> elements into a single list item.
1472
1473	11.15. <note> element
1474
1475	Can be used to add a note, usually indented by a few characters. It
1476	should contain one or more <t> child elements.
1477
1478	11.16. <parse-xml> element
1479
1480	This element instructs the processor to parse the contents as XML and
1481	to warn when there's a problem (requires either MSXML or Saxon8 or
1482	newer).
1483
1484	11.17. <prose> element
1485
1486	This element can be used inside <reference> to add plain text (before
1487	the date, when present).
1488
1489	11.18. <q> element
1490
1491	This element is like the "q" element in [HTML].
1492
1493	11.19. <ref> element
1494
1495	This element is a simplified variant of the <xref> element, in that
1496	no "target" attribute needs to be specified, instead the text
1497	contents acts as identifier. That in itself wouldn't be terribly
1498	useful, but together with the <anchor-alias>, it allows referring to
1499	other parts of the document with minimal additional markup.
1500
1501	For instance, given an alias definition such as
1502
1503	<section title="Test" anchor="test">
1504	<x:anchor-alias value="alias1"/>
1505	<x:anchor-alias value="alias 2"/>

1512
1513	Documentation RFC2629 through XSLT March 2011
1514
1515
1516	the following simple references
1517
1518	<x:ref>test</x:ref>
1519	<x:ref>alias1</x:ref>
1520	<x:ref>alias 2</x:ref>
1521
1522	are equivalent to...:
1523
1524	<xref target="test">test</xref>
1525	<xref target="test">alias1</xref>
1526	<xref target="test">alias 2</xref>
1527
1528	11.20. <source> element
1529
1530	Can be used to enhance a <reference> with information about the
1531	location for the XML source. This can be used by the <xref>
1532	processing code to automatically extract the target section number.
1533
1534	For example:
1535
1536	...
1537	<xref target="RFC2616" x:fmt="of" x:rel="#PUT" />
1538	...
1539
1540	<reference target="RFC2616"/>
1541	...
1542	<x:source href="rfc2616.xml"/>
1543	...
1544
1545	11.21. <sup> element
1546
1547	This element is like the "sup" element in [HTML].
1548
1549	Note: the down conversion to RFC2629 format replaces "x^y" by "x^y".
1550
1551	11.22. Extensions to Xml2rfc <artwork> element
1552
1553	Sometimes, artwork occurs inside lists. To get it indent properly in
1554	xml2rfc's text output, it needs to be indented in the source. This
1555	is sub-optimal, as this whitespace will also appear in the HTML
1556	output, where it's already indented due to HTML's semantics.
1557
1558	As a workaround, a "x:indent-with" attribute can be specified,
1559	containing a string that will be prepended to each line when
1560	"clean-for-DTD.xslt" is run (see Section 12.4).

1571
1572	11.23. Extensions to Xml2rfc <iref> element
1573
1574	The extension attribute below is allowed on the standard <iref>
1575	element:
1576
1577	o x:for-anchor specifies that the <iref> will also be automatically
1578	inserted whenever the specified anchor is cross-referenced -- this
1579	may save entering lots of <iref> instances. As a special case, a
1580	value of "" (empty string) refers to the anchor attribute of the
1581	closest ancestor.
1582
1583	11.24. Extensions to Xml2rfc <list> element
1584
1585	The extension attribute below is allowed on the standard <list>
1586	element:
1587
1588	o x:indent specifies the amount of indentation for list items in
1589	hanging lists. This can be useful when the output format, such as
1590	XSL-FO, does not support automatical formatting. The value takes
1591	an XSL-FO width, such as "5em". The default is _length of longest
1592	label in characters_ times _0.8em_.
1593
1594	Also, the <list> element can take <x:lt> child elements instead of
1595	<t>, allowing to insert multiple paragraphs into a single list item.
1596
1597	11.25. Extensions to Xml2rfc <rfc> element
1598
1599	The extension attributes below are allowed on the standard <rfc>
1600	element:
1601
1602	o grddl:transformation can be used to reference a GRDDL transform.
1603
1604	o x:maturiy-level can be used to specify the IETF Standards Track
1605	Maturity Level of "proposed", "draft" or "internet" (see Section
1606	4.1 of [RFC2026]).
1607
1608	11.26. Extensions to Xml2rfc <section> element
1609
1610	The extension attribute below is allowed on the standard <list>
1611	element:
1612
1613	o x:fixed-section-number can be used to specify a fixed section
1614	number. This can be useful when formatting historic documents
1615	that used a different numbering style.

1628	11.27. Extensions to Xml2rfc <xref> element
1629
1630	Three extension attributes are allowed on the standard <xref>
1631	element:
1632
1633	1. x:sec can be specified to point to a specific section of the
1634	referenced document,
1635
1636	2. x:rel may specify a relative reference to use when linking into
1637	the referenced document (if linking by section number is not
1638	available),
1639
1640	3. x:fmt defines the text format to be used.
1641
1642	The following formats are defined for the x:fmt attribute:
1643
1644	, (Comma) [_reference_], Section _sec_
1645
1646	() [_reference_] (Section _sec_)
1647
1648	anchor Like the default format, but without brackets.
1649
1650	of Section _sec_ of [_reference_]
1651
1652	number _sec_
1653
1654	none No output (can be used to have xrefs to references without
1655	having them rendered as such)
1656
1657	sec Section _sec_
1658
1659	These extensions are currently only supported for <xref> elements
1660	without child nodes.
1661
1662	If the processor knows how to reference the target section, it will
1663	generate a link directly to the target section, such as in [RFC2119],
1664	Section 5.

1684	12. Utilities
1685
1686	12.1. Checking References
1687
1688	"check-references.xslt" can be used to check all references to RFC-
1689	and ID-series IETF publications and to W3C publications (note this
1690	script requires local copies of
1691	<ftp://ftp.isi.edu/in-notes/rfc-index.xml> and
1692	<http://www.w3.org/2002/01/tr-automation/tr.rdf> and will use the XML
1693	status information provided at <http://tools.ietf.org/>).
1694
1695	If the document is supposed to be published on the IETF standards
1696	track, the desired level can be specified using the parameter
1697	"intended-level" as 'proposed', 'draft' or 'internet'.
1698	Alternatively, it can be specified inside the document using the
1699	attribute x:maturity-level on the <rfc> element.
1700
1701	Note: Downward references should be annotated using the <annotate>
1702	element, containing an <xref> to [BCP97].
1703
1704	When an XSLT 2.0 processor is used, links in the document can be
1705	checked as well using the "link-check" paramerer ('yes' or 'no').
1706	Note that this only works for http links to documents of type text/*.

1780	o for RFCs, the name attribute must be "RFC", and the value
1781	attribute must be the number of the RFC,
1782
1783	o for Internet Drafs, the name attribute must be "ID" or "Internet-
1784	Draft", and the value attribute must be the file name of the draft
1785	(including the two-digit running number, but excluding a file
1786	extension),

1792
1793	Documentation RFC2629 through XSLT March 2011
1794
1795
1796	o for W3C documents, the name attribute must be "W3C", must start
1797	with "W3C ", or must start with "World Wide Web Consortium ", and
1798	the value attribute must be the "shorthand" name of the
1799	specification, such as "REC-xml-19980210".
1800
1801	Note: this stylesheet will need network access to check links and
1802	status of Internet Drafts. When running a Java-based XSLT engine,
1803	you may have to supply Java system properties specifying the HTTP
1804	proxy to be used, such as "-Dhttp.proxyHost=hostname
1805	-Dhttp.proxyPort=80".
1806
1807	12.2. Generating Graphs from References
1808
1809	"gen-reference-graph.xslt" generates a graph of RFC dependencies,
1810	using the same base data as in "check-references.xslt" (see
1811	Section 12.1). Its output is a "dot" file, to be processed by
1812	GraphViz (see <http://www.graphviz.org/>).
1813
1814	The picture below shows the RFC dependencies in RFC2629.
1815
1816
1817	12.3. Producing reference entries for books
1818
1819	"amazon-asin.xslt" uses the Amazon web services to generate a
1820	<reference> element for a given ASIN (ISBN).
1821
1822	For instance:
1823
1824	<?xml version="1.0" encoding="utf-8"?>
1825	<references>
1826	<reference target="urn:isbn:0134516591">
1827	<front>
1828	<title>Simple Book, The: An Introduction to Internet Management,
1829	Revised Second Edition</title>
1830	<author surname="Rose"
1831	fullname="Marshall T. Rose" initials="M. T. ">
1832	<organization/>
1833	</author>
1834	<author surname="Marshall"
1835	fullname="Rose T. Marshall" initials="R. T.">
1836	<organization/>
1837	</author>
1838	<date year="1996" month="March"/>
1839	</front>
1840	<seriesInfo name="Prentice Hall" value=""/>
1841	</reference>
1842	</references>

1850
1851
1852	Note that the resulting XML usually requires checking, in this case
1853	Amazon's database is playing tricks with Marshall's name...
1854
1855	12.4. Down-converting to RFC2629bis DTD
1856
1857	"clean-for-DTD.xslt" can be used to down-convert some extensions to a
1858	format that is supported by the base xml2rfc distribution. Note that
1859	these extensions are experimental (feedback appreciated).
1860
1861	The following mappings are done:
1862
1863	o <iref> elements inside <artwork> elements are moved in front of
1864	the enclosing <figure> element.
1865
1866	o <xref> elements inside <artwork> are expanded just like in regular
1867	text (that is, the markup is stripped, but the element is replaced
1868	by the applicable replacement text).
1869
1870	o <x:anchor-alias> elements get stripped.
1871
1872	o <x:bcp14> elements get stripped.
1873
1874	o <x:bb>, <x:bc> and <x:bt> elements get stripped.
1875
1876	o <x:blockquote> elements get converted to indented text (through a
1877	<list> element).
1878
1879	o <x:dfn> elements get stripped.
1880
1881	o <x:h> elements get stripped.
1882
1883	o <x:link> elements get stripped.
1884
1885	o <x:lt> elements get collapsed into a single <lt> element with
1886	added <vspace> added to simulate paragraph breaks.
1887
1888	o <x:note> elements get converted to indented text (through a <list>
1889	element).
1890
1891	o <x:q> elements get stripped, with apostrophes added around the
1892	text.
1893
1894	o <x:prose> elements are transformed into <seriesInfo> elements
1895	(which is an abuse of the element and only a workaround until
1896	xml2rfc gets a matching extension).
1897
1898	o <x:ref> elements get replaced by <xref> elements, targetting
1899	either the anchor or another anchor with matching <x:anchor-alias>

1909
1910	12.5. Extracting artwork
1911
1912	With "extract-artwork.xslt", artwork elements named through the
1913	"name" attribute can be extracted. This can be used to automatically
1914	check their syntax (for instance, when ABNFs appear within a figure
1915	element).
1916
1917	For instance:
1918	saxon rfc3986.xml extract-artwork.xslt name=uri.abnf
1919
1920	In addition, artwork of a specific type can be extracted, such as
1921	with:
1922	saxon rfc3986.xml extract-artwork.xslt type=abnf
1923
1924	When extracting by type, artwork elements with a specified name can
1925	be excluded; this can be handy when the document uses some kind of
1926	schema language, and an appendix contains the collected schema,
1927	repeating definitions from earlier on. Example:
1928	saxon rfc3986.xml extract-artwork.xslt type=abnf except-name=clschm
1929
1930	12.6. GRRDL
1931
1932	"rfc2629grddl.xslt" extracts RDF information. This is experimental
1933	work-in-progress. See <http://www.w3.org/TR/grddl/> for more
1934	information.

2696	The prolog of the XML document can both be used to refer to an

2698	[XML]):
2699

2701	<?xml-stylesheet type='text/xsl' href='rfc2629.xslt' ?>

2710	<!-- you may need this for UAs that do not read external DTDs -->
2711	<!ENTITY nbsp

2713
2714	<!-- allow later RFC2616 reference using "&rfc2616;" -->
2715	<!-- the data will be fetched from xml.resource.org -->
2716	<!ENTITY rfc2616 PUBLIC
2717	"http://xml.resource.org/public/rfc/bibxml/reference.RFC.2616.xml">
2718
2719	<!-- allow a custom reference using "&mydraft;" -->
2720	<!-- the data will be fetched from the same location as the
2721	source file -->
2722	<!ENTITY mydraft PUBLIC "reference.mydraft.xml">
2723	]>
2724
2725	Note: including entities from a remote site will not work in Firefox,
2726	see <https://bugzilla.mozilla.org/show_bug.cgi?id=22942>.
2727
2728	C.2. Customization
2729
2730	The XSLT code can be customized by creating a custom XSLT file that
2731	uses <xsl:import> to include the original code, and just overrides
2732	particular rules.

2745	Documentation RFC2629 through XSLT March 2011
2746
2747
2748	For instance, the code below overrides several attributes in
2749	"rfc2629toFO.xslt", changing the color, spacing and font family for
2750	headers.
2751
2752	<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
2753	version="1.0">
2754
2755	<xsl:import href="rfc2629toFO.xslt"/>
2756
2757	<xsl:attribute-set name="h1">
2758	<xsl:attribute name="color">darkblue</xsl:attribute>
2759	<xsl:attribute name="font-family">sans-serif</xsl:attribute>
2760	<xsl:attribute name="space-before">24pt</xsl:attribute>
2761	</xsl:attribute-set>
2762
2763	<xsl:attribute-set name="h2">
2764	<xsl:attribute name="color">darkblue</xsl:attribute>
2765	<xsl:attribute name="font-family">sans-serif</xsl:attribute>
2766	<xsl:attribute name="space-before">18pt</xsl:attribute>
2767	<xsl:attribute name="space-after">3pt</xsl:attribute>
2768	</xsl:attribute-set>
2769
2770	<xsl:attribute-set name="h3">
2771	<xsl:attribute name="color">darkblue</xsl:attribute>
2772	<xsl:attribute name="font-family">sans-serif</xsl:attribute>
2773	<xsl:attribute name="space-before">16pt</xsl:attribute>
2774	<xsl:attribute name="space-after">2pt</xsl:attribute>
2775	</xsl:attribute-set>
2776
2777	</xsl:transform>
2778
2779	Note: the name for the attribute sets may change in the future as
2780	more working is done with respect to customizability. In any
2781	case, overriding the settings in a separate file will be easier to
2782	maintain. Please contact the author if you find yourself trying
2783	to override style definitions that currently do not use attribute
2784	sets.
2785
2786	Note: the CSS style information used in "rfc2629.xslt" can be
2787	overriden in a similar (but less granular) way: just overwrite the
2788	template called "insertCss". As for XSL-FO, the class names may
2789	change in future.

2804	Appendix D. Producing the IETF 'Boilerplate'
2805
2806	Various attributes of the "<rfc>" element plus some child elements of
2807	"<front>" affect the automatically generated parts of the front page,
2808	such as the tabular information at the beginning, the "Status Of This
2809	Memo", and the "Copyright Notice".
2810
2811	When submitting an Internet Draft, this "boilerplate" is checked by
2812	"Idnits" (<http://tools.ietf.org/tools/idnits/>) for compliance with
2813	the current Intellectual Property rules, and thus it is important to
2814	set the correct values.
2815
2816	Furthermore, the RFC Production Center uses RFC2629-based tools to
2817	generate the final RFC text, so the more accurate the supplied
2818	information is, the less additional work is left, and the risk for
2819	errors in producing the final (and immutable!) document is reduced.
2820
2821	Note: this only applies to the case when IETF documents are
2822	produced. The "private" processing instruction allows to switch
2823	off most of the autogeneration logic.
2824
2825	D.1. The /rfc/@ipr Attribute
2826
2827	As of the time of this writing, this attribute value can take a long
2828	list of values. As frequently, this is not the result of a grand
2829	plan, but simply for historic reasons. Of these values, only a few
2830	are currently in use; all others are supported by the various tools
2831	for backwards compatibility with old source files.
2832
2833	Note: some variations of the boilerplate are selected based on the
2834	document's date; therefore it is important to specify the "year",
2835	"month" and "day" attributes of the "<date>" element when
2836	archiving the XML source of an Internet Draft on the day of
2837	submission.
2838
2839	_Disclaimer: THIS ONLY PROVIDES IMPLEMENTATION INFORMATION. IF YOU
2840	NEED LEGAL ADVICE, PLEASE CONTACT A LAWYER._ For further information,
2841	refer to <http://trustee.ietf.org/docs/IETF-Copyright-FAQ.pdf>.
2842
2843	Finally, for the current "Status Of This Memo" text, the
2844	"submissionType" attribute determines whether a statement about "Code
2845	Components" is inserted (this is the case for the value "IETF", which
2846	also happens to be the default). Other values, such as
2847	"independent", suppress this part of the text.

2973
2974	The attribute values "full3667", "noModification3667" and
2975	"noDerivatives3667" are similar to their counterparts above, except
2976	that they use text specified in RFC 3667 (February 2004).
2977
2978	D.1.2.4. Historic Values: '*2026'
2979
2980	The attribute values "full2026" and "noDerivativeWorks2026" are
2981	similar to their counterparts above, except that they use text
2982	specified in RFC 2026 (October 1996).
2983
2984	The special value "none" was also used back then, and denied the IETF
2985	any rights beyond publication as Internet Draft.
2986
2987	D.2. The /rfc/@category Attribute
2988
2989	For RFCs, the "category" determines the "maturity level" (see Section
2990	4 of [RFC2026]). The allowed values are "std" for "Standards Track",
2991	"bcp" for "BCP", "info" for "Informational", "exp" for
2992	"Experimental", and "historic" for - surprise - "Historic".
2993
2994	For Internet Drafts, the category attribute is not needed, but _will_
2995	appear on the front page ("Intended Status"). Supplying this
2996	information can be useful, because reviewers may want to know.
2997
2998	Note: the Standards Track consists of "Proposed Standard", "Draft
2999	Standards", and "Internet Standard". These do not appear in the
3000	boilerplate, thus the category attribute doesn't handle them.
3001	However, this information can be useful for validity checkers, and
3002	thus "rfc2629.xslt" supports an extension attribute for that
3003	purpose (see Section 11.25 for details).
3004
3005	D.3. The /rfc/@submissionType Attribute
3006
3007	The RFC Editor publishes documents from different "document streams",
3008	of which the "IETF stream" of course is the most prominent one.
3009	Other streams are the "independent stream" (used for things like
3010	administrative information or April 1st RFCs), the "IAB stream"
3011	(Internet Architecture Board) and the "IRTF stream" (Internet
3012	Research Task Force).
3013
3014	Not surprisingly, the values for the attribute are "IETF" (the
3015	default value), "independent", "IAB", and "IRTF".
3016
3017	_The values "IAB" and "IRTF" are supported by rfc2629.xslt, but not
3018	yet allowed by the DTD (waiting for release 1.36 of xml2rfc)._

3024
3025	Documentation RFC2629 through XSLT March 2011
3026
3027
3028	Historically, this did not affect the final appearance of RFCs,
3029	except for subtle differences in Copyright notices. Nowadays (as of
3030	[RFC5741]), the stream name appears in the first line of the front
3031	page, and it also affects the text in the "Status Of This Memo"
3032	section.
3033
3034	For current documents, setting "submissionType" attribute will have
3035	the following effect:
3036
3037	o For RFCs, the stream name appears in the upper left corner of the
3038	first page (in Internet Drafts, this is either "Network Working
3039	Group", or the value of the "<workgroup>" element).
3040
3041	o For RFCs, if affects the whole "Status Of This Memo" section (see
3042	Section 3.2.2 of [RFC5741]).
3043
3044	o For all RFCs and Internet Drafts, it determines whether the
3045	"Copyright Notice" mentions the Copyright on Code Components (see
3046	TLP, Section "Text To Be Included in IETF Documents").
3047
3048	Note: as of Version 1.35, "xml2rfc" (as opposed to "rfc2629.xslt")
3049	does _not_ implement support values other than "IETF" or
3050	"independent".
3051
3052	D.4. The /rfc/@consensus Attribute
3053
3054	_Supported by rfc2629.xslt, but not yet allowed by the DTD (waiting
3055	for release 1.36 of xml2rfc)._
3056
3057	For some of the publication streams (see Appendix D.3), the "Status
3058	Of This Memo" section depends on whether there was a consensus to
3059	publish (again, see Section 3.2.2 of [RFC5741]).
3060
3061	The "consensus" attribute ("yes"/"no", defaulting to "yes") can be
3062	used to supply this information. The effect for the various streams
3063	is:
3064
3065	o "independent" and "IAB": none.
3066
3067	o "IETF": mention that there was an IETF consensus.
3068
3069	o "IRTF": mention that there was a research group consensus (where
3070	the name of the research group is extracted from the "<workgroup>"
3071	element).

3082
3083
3084	D.5. The /rfc/@number Attribute
3085
3086	For RFCs, this attribute supplies the RFC number.
3087
3088	D.6. The /rfc/@docName Attribute
3089
3090	For Internet Drafts, this specifies the draft name (which appears
3091	below the title). The file extension is _not_ part of the draft, so
3092	in general it should end with the current draft number ("-", plus two
3093	digits).
3094
3095	Note: "Idnits" (<http://tools.ietf.org/tools/idnits/>) checks the
3096	in-document draft name for consistency with the filename of the
3097	submitted document.
3098
3099	D.7. The /rfc/@obsoletes Attribute
3100
3101	The RFC Editor maintains a database
3102	(<http://www.rfc-editor.org/rfc.html>) of all RFCs, including
3103	information about which one obsoletes which. Upon publication of an
3104	RFC, this database is updated from the data on the front page.
3105
3106	This attribute takes a list of comma-separated RFC _numbers_. Do
3107	_not_ put the string "RFC" here.
3108
3109	D.8. The /rfc/@updates Attribute
3110
3111	This is like "obsoletes", but for the "updates" relation.
