I disagree. I think xmlns="http://www.w3.org/1999/html" is fine in  
HTML because it just states what is already implied. But I think  
allowing attributes with no meaning to validate will just reenforce  
the idea that they are meaningful. If you use them, fine, but you'll  
have a validation error there that will warn you that this is no HTML.

I know I suggested xml:lang before, but that was when I thought it  
was parsed in HTML. Now I think a more clever approach would be to  
allow html:lang to validate in XHTML, because XHTML already mandates  
that html:lang be taken into account when determining the language.

As for xml:id, why not use "id" purely and simply? It works with both  
HTML and XHTML anyway.
