It's a design issue that goes beyond the schema itself :=) ...

IMHO, since namespaces are aimed to disambiguate element names, ns1:elt
and ns2:elt should be considered as having a different semantic...

And if you import the definitions using unqualified types, you hide this
since you get similar element names from different namespaces that are
expected to have the same meaning !

Wouldn't it be simpler to use a single namespace then ?
