Aloha. I'm in need of a little enlightenment (or a club over the head) in
regards to the proper use of namespaces for the following scenario.
I've got two schemas, A & B, that each define an element named EltC. A and
B both use the same targetNamespace. A and C are both defined by a
"standards body" so I do not want to modify their definitions.
If I want to create another schema, Z, which aggregates A & B (i.e. A & B
are children in Z), I have the problem of a duplicate definition of EltC. I
have, to this point, tried creating Z by <include> or <import> of A & B.
Both of which give the problem of a duplicate definition. This seems so be
an issue of polymorphism to me.
My question is... how can I properly <import> (or <include>) A & B in Z such
that there is not this definition conflict? Is this even possible if A & B
have the same targetNamespace value?
fyi - The actual application is that A and B correspond to Request and
Response -type definitions and Z then is an interface that defines the
interaction.
(Abbreviated) Schema definitions follow...
Mahalo for any suggestions.
