48  This document describes a set of XSLT transformations that can be used to
49  transform RFC2629-compliant XML (see <xref target="RFC2629"/>) to various
50  output formats, such as HTML and PDF. The main topics are 
51  <list style="symbols">
52    <t>compliance to the xml2rfc XML element set (<xref target="supported.elements"/>),</t>
53    <t>support for xml2rfc processing instructions (<xref target="processing.instructions"/>),</t>
54    <t>the names of anchor elements generated in HTML and PDF output (<xref target="anchors"/>),</t>
55    <t>various XSLT engines that can be used (<xref target="xslt.engines"/>),</t>
56    <t>outputting HTML (<xref target="output.html"/>) and XHTML (<xref target="output.xhtml"/>),</t>
57    <t>outputting CHM (Compiled Microsoft Help, <xref target="output.chm"/>),</t>
58    <t>outputting PDF (<xref target="output.pdf"/>),</t>
59    <t>extensions to the xml2rfc vocabulary (<xref target="extensions"/>).</t>
60    <t>various utilities (<xref target="utilities"/>).</t>
61  </list>

79  The first set contains (hopefully) generally useful extensions, see

83  The second set is used for change and issue tracking and currently is not
84  documented here. Please email the author in case

673  PDF output can also be produced directly from (X)HTML. One simple approach
674  is to rely on the browser's printing function, and to use a printer driver
675  that produces PDF. Depending on the brower's CSS capabilities, the output
676  will behave properly with respect to table breaks etc.
677</t>
678<t>
679  An alternative is PrinceXML (see <eref target="http://www.princexml.com/"/>),

681  information.

1174  When an XSLT 2.0 processor is used, links in the document can be checked as well
1175  using the <spanx style='verb'>link-check</spanx> paramerer ('yes' or 'no').
1176  Note that this only works for http links to documents of type text/*.

1350<section title="Extracting artwork" anchor="extract-artwork">
1351<t>
1352  With <spanx style="verb">extract-artwork.xslt</spanx>, artwork elements
1353  named through the "name" attribute can be extracted. This can be used
1354  to automatically check their syntax (for instance, when ABNFs appear
1355  within a figure element).
1356</t>
1357<figure><preamble>For instance:</preamble>
1358<artwork type="example">saxon rfc3986.xml extract-artwork.xslt name=uri.abnf
1359</artwork>
1360</figure>
1361<t>
1362  In addition, artwork of a specific type can be extracted, such as with:
1363</t>
1364<figure>
1365<artwork type="example">saxon rfc3986.xml extract-artwork.xslt type=abnf
1366</artwork>
1367</figure>
1368<t>
1369  When extracting by type, artwork elements with a specified name can be
1370  excluded; this can be handy when the document uses some kind of schema
1371  language, and an appendix contains the collected schema, repeating definitions
1372  from earlier on. Example:
1373</t>
1374<figure><artwork type="example">saxon rfc3986.xml extract-artwork.xslt type=abnf except-name=clschm
1375</artwork></figure>

2353<t>
2354  The <spanx style="verb">ipr</spanx> specifies what kind of text is generated
2355  for the "Status Of This Memo" and "Copyright Notice" sections on the front
2356  page. When submitting an Internet Draft, the "boilerplate" is checked
2357  by "Idnits" (<eref target="http://tools.ietf.org/tools/idnits/"/>) for compliance with the current Intellectual Property rules, and thus
2358  it's important to set the correct value.
2359</t>
2360<t>
2361  As of the time of this writing, the attribute value can take a long list of values. As
2362  frequently, this is not the result of a grand plan, but simply for historic
2363  reasons. Of these values, only a few are currently in use; all others are
2364  supported by the various tools for backwards compatibility with old source
2365  files.
2366</t>
2367<x:note>
2368  <t>
2369    <x:h>Note:</x:h> some variations of the boilerplate are selected based
2370    on the document's date; therefore it is important to specify the "year",
2371    "month" and "date" attributes when archiving the XML source of an Internet
2372    Draft on the day of submission.
