When I looked through these bugs most of the issues were related to the  
fact that we allowed xmlns="" declarations on HTML elements. I reported as  
much in some IRC log a while back. As far as I can tell this does not  
affect your proposal as it does not allow declarations on HTML elements.

So the Opera experiment with namespaces can probably considered as  
evidence for not doing special stuff with xmlns attributes specified on  
HTML elements. For anything else, such as claiming it's not harmful to  
allow this on "non-HTML" elements, it can probably not be used and we'd  
need to find some other data point.
