I am delighted to see this stated so cleanly and fully support it. The
message is clear for XSchema - we can and must address namespaces.
Fortunately I don't think it's too difficult. For the others I hope that
this view filters through to the WGs :-).

I agree with Paul that XPointer should have namespace aware components. For
example, it's  perfectly reasonable for someone to ask "are there any
mathematical or chemical equations in this document?" At present they would
have to search for 
descendant(1,MathML:EQN) or descendant(CML:REACTION) and *hope* that the
authors had used 'common' prefixes. But this will assuredly break. So
really they should be searching for (1,http://www.ams.org.MathML:EQN) or
whatever.
