...agreed but the author of the XML should still leave the namespace
declarations in the XML - just because a by-product of making them
#FIXED is that they are also defaulted, doesn't mean they should be
removed from the XML - thats just frustrating.

I've always thought augmenting XML through validation is a really bad
idea - who wants to wade through a DTD to get the full picture?  (and
then have to validate *every* time the XML is read)

I guess we all know DTDs, XML and namespaces don't play well together
- its just a shame  its used so often...
