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>

641  PDF output can also be produced directly from (X)HTML. One simple approach
642  is to rely on the browser's printing function, and to use a printer driver
643  that produces PDF. Depending on the brower's CSS capabilities, the output
644  will behave properly with respect to table breaks etc.

647  An alternative is PrinceXML (see <eref target="http://www.princexml.com/"/>),

649  information.

1008  Sometimes, artwork occurs inside lists. To get it indent properly in xml2rfc's

1010  this whitespace will also appear in the HTML output, where it's already
1011  indented due to HTML's semantics.
1012</t>
