Speaking of reckless recommendations, has anyone previously given thought to
namespaces of the form:

<np1:root  xmlns:np1="http://www.example.com/ns1"
xmlns:np2="http://www.example.com/ns2">

   <np1:foo/>
   <np2:bar>
      <np2:np1:baz/> <!-- this one -->
   </np2:bar>
</np1:root>


I know this is disallowed by Namespaces in XML Rec, but to me it could be
helpful for the types of namespace mixing pointed out by Arjun Ray awhile
back.

For the np2:np1:baz element above, the local name baz is interpreted to be
qualified by three distinct namespaces: ../ns1, ../ns2, and the hybrid
../ns1|../ns2 (signified by either np1:np2:baz for np2:np1:baz; order of
qualification is irrelevant).

The point is not to solve the problem of needing some semantic knowledge in
order to properly mix two namespaces: some function still needs to know
which elements get tagged with both their original namespace and the
overarching namespace. But it at least allows just _one_ function to have to
know-- the rest can just stupidly parse the qualified names, with awareness
of either one or both qualifiers.

Just thinking out loud...
