I mildly disagree.  The main problem is with the namespace spec, which lets 
the matter float about with its vague notions of "global attributes", but I 
think precedence in other specs such as XSLT suggests that RDF should only 
require the qualification within elements not in the RDF namespace, and in 
fact that the qualification should be forbidden on attributes of elements in 
the RDF namespace.

Strongly agreed.

Seems reasonable to me.

I do wish a more radical reformation of containers could be undertaken.
