If we're intent on producing an "HTML 5" specification which introduces
enhancements beyond improving the form controls etc I don't see why we are
debating the content model of DL's etc in this forum? Surely we should
discuss it in the context of XHTML 2.0 and when that is released as a
final recommendation cherry pick the good bits (DLs, sections etc) and
back port them to HTML 5. If XHTML 2.0 becomes adopted in user agents,
like mozilla <https://bugzilla.mozilla.org/show_bug.cgi?id=161463>, surely
it is easier for them to also support HTML 5 if they only have a few
important areas of difference, like the web forms enhancements.

Perhaps we should stop thinking of this as HTML 5 and more as EHTML (for
Enhanced HTML) so we can introduce new version numbering etc. We could
start off with EHTML 1 which introduces the Web Forms stuff, then EHTML 2
could be released later which back ports XHTML 2's good features (as well
as new web forms stuff). I think this might make evangelising EHTML a bit
easier, it worked for DHTML after all!
