Thanks for the speedy response.

Hmm although currently when I'm geerating html or xhtml from something
else I either go to the trouble of lifting lists out of paragraphs, or I
map paragraphs to div, so ol in p doesn't really affect my existing
content, but a lot of my existing content would be invalid due to the
change in the content model for div, not allowing mixed block level
content. Personally I don't mind if you invalidate my content (I'll
adapt to fit whatever:-) but I mention this as in general I know HTML5
design strives for good comaptibility with existing content.

urg, I'd argue that that could be changed (but not in this message,
given your wording I'll assume that this is a given).

Would it be possible (in text/html and /xml) to hide nested lists in some new
inline-element-that-takes-block-content  so
<p>blah blah blah
more text

I think so, yes, if you allow the content modesl to differ too much (or
at all) the story about when to use xml serialisation and when not to
use it gets even more complicated.

I'm interested thanks, but to be honest I've only been half following
html5 (MathML and the day job taking up time:-) so would be a little
wary of giving me write access, not having observed any previous
discsussion (or implementation constraints such as the one you quote
above) however mostly I use d.p.carlisle@googlemail.com for google docs
stuff if you do wish to give me access. I may just watch the spreadsheet
for a while to get a feel for how things are going. I see there's a
parallel chat channel attatched to it.....
