The working group resolved to have XHTML 2 be in the same namespace as 
XHTML 1 some time ago.  A note to that effect is in the current editors 
draft (not public).  However, documents that are in development are in 
temporary namespaces as a matter of course at the W3C so that there is 
no possibility of pollution while development is ongoing.  As soon as 
the current round of edits is complete, a new public draft will be made 
available.  Sorry for the confusion.
