Oh. Then we disagree on the outcomes :(

I think we agree on the principle.

Saying that the attributes in HTML are in the null namespace does not  
anticipate anything that some future spec might say, nor does it conflict  
with any current draft I know of, with regard to XML - it is in fact  
perfectly in line with the specs and implementations that have emerged in  
the 10 years of XML.

It *also* simplifies the process of building applications, and the process  
of explaining how to add aria to a new XML or non-XML spec.

These two reasons are why I believe the PFWG will adopt the solution I  
suggested above as its preferred model for both HTML and XML languages.

cheers
