It seems that XHTML2 WG changed their mind and they plan to use
http://www.w3.org/1999/xhtml namespace for XHTML2, see:


"Just to clarify; we do not believe that XHTML2 is terribly different
from XHTML 1.1.  And it does not use a different namespace." -- Shane P.


"ACTION: Shane update xhtml2 text on namespaces to make it clear that we
are planning to try to re-use the xhtml1 namespace."

Well, I don't think that having two languages (HTML5 and XHTML2) with a
different semantics and element sets in the same namespace makes sense.
This is real issue which should be resolved quickly. Or will be there
toss between HTML and XHTML WGs on right to use this namespace?

If the namespaces will be the same then we definitively should use
something like <html version="5.0"> to be able to differentiate between
XHTML2 and XML serialization of HTML5.


I'm CC'ing this message also to a public XHTML2 mailing list.
