Sounds fine (if I've read that correctly... it's a bit difficult to
parse on the first go) but you could just use the hierarchical nature
of XML to signify what's what (wrap each type in an element), if for
example there were two types that weren't in a namespace.

Really - critically important?

Sorry Ken - parse failure on that whopper of a sentence! I think I
get the semantics even if the syntax causes problems... :)
I've never come across the aggregation of multiple XML sources where
I've thought "good job they are in different namespaces otherwise I'd
be stuck here"... but I have come across many single XML documents
with several namespaces which do nothing more than make processing
that XML needlessly more complicated.
