Hi!

Well, as long as this doesn't mean @rev may be dropped from (future
domains of) RDFa? I mean, if HTML5 "wins", and e.g. XHTML2
applications will be scarce to non-existant (and when XHTML 1.1(+RDFa)
"eventually" becomes a legacy format), having no support for @rev may
have a bad effect for lots of use cases.

It depends on other things, but since AFAIK @rev reduces the need for
repetition in a lot of cases, such as describing
memberships/composition (e.g. as I describe in
<http://lists.w3.org/Archives/Public/public-rdf-in-xhtml-tf/2008Jan/0091.html>),
it (probably) has a direct effect on the ease of building end-user
applications that produce RDFa (since e.g. repetition of uri:s
requires parallell maintenance to handle the indent).

[Digression: It's a complex issue of course, but I'm uncomfortable
with the way HTML5 seems to drop stuff that are relevant to many good
things, e.g. RDFa. Well, @profile and @rev to date(?), but who knows
what else may be thrown out since "nobody uses it".. I hope for a
future for XHTML2. (Or even something like "web document markup" and
an extension like "web application markup", but that's another
story.)]

Just my two cents.

Best regards,
Niklas
