Well, actually, they do not. The URI used for a namespace has nothing
to do with the URI for any schema document. To use another schema, you
need to import (or include, if you want it to use the same target
namespace) it. You haven't done that. You also have not declared a
target namespace for either of the two schemas, but you use
elementFormDefault='qualified', as if you had so declared.
Maybe one or both of those processors tried to use the namespace as a
hint, and assumed you wanted to import the schema document at the
namespace URI, but who knows? That is not mandated by the XML Schema
Recommendation.
In principle, you should be able to import schemas that refer to each
other, but it is asking for trouble and I have heard that some
processors have trouble with circular imports. I'd avoid them, if I
were you.
I suggest you figure out what namespaces you want to use, if any,
correct the schemas accordingly, decide which one should import which,
and get rid of the circular references.
