Right. XHTML 1.0 also doesn't allow arbitrary attributes, so a role  
attribute in the http://www.w3.org/1999/xhtml namespace does not make it  
any more conforming XHTML 1.0 than the role attribute in no namespace or  
in the http://www.w3.org/TR/xhtml2 namespace.

Agree, but there are two namespaced role attributes.

I'm interested in limiting the ways to do things with ARIA to a minimum,  
with the following constraints:

   * We should support existing content.
   * It should be possible to use in both (X)HTML and other vocabularies  
without scripting.
   * The UA processing rules should be the same for both HTML and XHTML.

If there is no content that relies on the role attribute in the  
http://www.w3.org/1999/xhtml namespace to be supported, then I would like  
support for it to be removed, but it is not overly important to me.
