I agree that you need namespaces and XML schemas.  This is only a
stopgap measure to provide half-baked "support".

If you construct a DTD which has all the elements from all the
schemas involved, complete with their prefix, then you might be able
to use that.  Of course, this means that you need to decide on a
prefix for your documents.  But at least you could get tags
completion this way.

I agree that it is painful, however, to construct a DTD for all
mixtures of schemas that you might need.  However, maybe you can get
away with making ONE DTD that contains ALL schemas that you work with.
