You could, but I don't think that is a valid position considering
the global scope intended for the SW.

I.e. when those two different QNames occur in
totally different serializations from totally different sources
totally ignorant of each other's use of namespaces, and 
ambiguity is introduced (needlessly) into the knowledge base
when those sources are syndicated because the resultant URIs
collide, that's really going to make for a robust and reliable SW.

Eh?
