A new XHTML 2.0 WD has been published on May 27, 2005
http://www.w3.org/TR/2005/WD-xhtml2-20050527/ 

It's the seventh publication and _not yet_ the last call of XHTML 2.0
One of the interesting thing I can notice so far is the "role"  
attribute.

I will make a deeper review.

[[[
This document is the seventh public Working Draft of this  
specification. It should in no way be considered stable, and should  
not be normatively referenced for any purposes whatsoever. This  
version includes an early implementation of XHTML 2.0 in RELAX NG  
[RELAXNG], but does not include the implementations in DTD or XML  
Schema form. Those will be included in subsequent versions, once the  
content of this language stabilizes.

Formal issues and error reports on this specification shall be  
submitted to www-html-editor@w3.org (archive). It is inappropriate to  
send discussion email to this address. Public discussion may take  
place on www-html@w3.org (archive).
