My own preference would be to use the lookupNamespaceURI() method on a
node, but that would imply we have a Level 3 DOM.  I suspect that
minidom will eventually provide this in some form.  ;-)

I don't think we have a good way to do that now, but it could be done
in a DOM-independent way by walking up the tree looking at namespace
declarations.
