Removed Elements The <appendix> element has been removed; to generate an appendix, place a <section> inside <back>. A.2. Changed Defaults Many attributes have lost their "default" value; this is to avoid having document semantics differ based on whether a DTD was specified and evaluated. Processors will handle absent values the way the Reschke Expires April 19, 2014 [Page 25]
Internet-Draft XML2RFC October 2013 default value was specified before. A.3. Changed Elements <artwork>: Has a set of new attributes: "name", "type", "src", "align", "alt", "width", and "height". (Section 2.5) <author>: The <organization> element is now optional. The "role" attribute was added. (Section 2.6) <date>: All attributes are now optional. (Section 2.13) <figure>: Has a set of new attributes: "suppress-title", "src", "align", "alt", "width", and "height". (Section 2.17) <iref>: Has a new "primary" attribute. (Section 2.20) <list>: The "style" attribute isn't restricted to a set of enumerated values anymore. The "hangIndent" and "counter" attributes have been added. (Section 2.22) <rfc>: The "ipr" attribute has gained additional values. The attributes "consensus", "iprExtract", "submissionType", and "xml: lang" have been added. (Section 2.33) <reference>: <annotation> allows adding prose to a reference. (Section 2.30) <references>: Can now appear multiple times, and carry a "title" attribute (so that normative and informative references can be split). (Section 2.31) <section>: The new "toc" attribute controls whether it will appear in the Table Of Contents. <iref> can now appear as direct child element. (Section 2.34) <t>: The "anchor" attribute can now be used as well, however there are restrictions on how they can be referred to. (Section 2.38) A.4. New Elements The following elements have been added: <annotation> (Section 2.3), <c> (Section 2.8), <cref> (Section 2.12), <format> (Section 2.18), <spanx> (Section 2.36), <texttable> (Section 2.39).

Internet-Draft XML2RFC October 2013 Appendix B. Proposed Future Changes [[anchor73: The list below is just a starting point.]] Allow multiple paragraphs in list items; eliminating the need to use <vspace> (see <http://greenbytes.de/tech/webdav/rfc2629xslt/ rfc2629xslt.html#ext.element.lt>). Make the <date> element optional; all of its content is optional already. Deprecate or remove the <format> element; right now it's not used for the generation of the plain text document anyway. Allow <reference>s that identify a document set such as a STD. Allow overriding the "anchor" attribute of an included <reference> element. Add a way to add prose to a reference that avoids abuse of <seriesInfo>. Extend <xref> so that subsection/anchors can be specified (see <http: //greenbytes.de/tech/webdav/rfc2629xslt/ rfc2629xslt.html#ext-rfc2629.xref>). Remove the "pageno" attribute which seems to be both undocumented and non-functional. Extend <figure> to support different types of artwork (such as by specifying certain type attribute values, see <http://greenbytes.de/ tech/webdav/rfc2629xslt/rfc2629xslt.html#artwork.types>), and also avoid having to markup code (such as ABNF) as "artwork". Also, it would be good if "code components" could be marked as such. Finally, even in preformatted text use of markup could be useful to support (a) references, or (b) highlighting the important bits (<http:// greenbytes.de/tech/webdav/rfc2629xslt/ rfc2629xslt.html#ext-rfc2629.artwork>). If contact information is changed to allow non-ASCII characters: add a place for a ASCII fallback (probably just for the author names). The content model for <postal> ought to be more strict to allow at most one of <city>, <region>, <code>, and <country>. Cleanup the set of overlapping attributes between <figure> and <artwork>.
