When I say 'unqualified' I mean just that. i.e. In no namespace.
I never use default namespace decls. They're evil. To 'protect' myself I'd
put xmlns='' on the qualified element.

I have the top-level element qualified and children unqualified. Exactly

I think it's safe to assume I'll get the namespace decls right.
