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>

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

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

666  information.

1025  Sometimes, artwork occurs inside lists. To get it indent properly in xml2rfc's
1026  text output, it needs to be indented in the source. This is sub-optimal, as
1027  this whitespace will also appear in the HTML output, where it's already
1028  indented due to HTML's semantics.

2297    as more working is done with respect to customizability. In any case,
2298    overriding the settings in a separate file will be easier to maintain.
2299    Please contact the author if you find yourself trying to override style
2300    definitions that currently do not use attribute sets.

2304    can be overriden in a similar (but less granular) way: just overwrite the
