xsi:type and namespaces

[Matthew Graham]

Hi,

I have checked the namespace behaviour issue - does <vr:interface> go to
<vs:interface> when you change the type to one defined in the vs:
namespace? The answer is no, even though the type may belong to a
different namespace, the element remains in its original namespace.

This makes sense: an element and its type are separate things and can
belong to different namespaces; although this is different from the
extensibility behaviour of substitution groups where the namespace of the
replaced element can be different but there you are replacing the element
directly not just changing its type. 

	Cheers,
