------- Additional Comments From sandygao@ca.ibm.com  2002-10-10 18:52 -------
Please read the following section in the spec:
http://www.w3.org/TR/xmlschema-1/#layer2
Especially the last paragraph (starting with NOTE:), right above "4.3":
"Given that the schemaLocation [attribute] is only a hint, it is open to 
applications to ignore all but the first <import> for a given namespace, ..."

So this is not a bug, because the spec allows it.

And I believe we *should* do it this way, because it encourages better Schema 
authoring practice: always have a *root* schema document for a given namespace, 
which includes or redefines other documents contributing to the same namespace.

Otherwise let's assume you have 10 schema documents that all refer to both 
B.xsd and C.xsd. If you decide to add another D.xsd to namespaceD, you'll have 
to update all 10 documents to import this new file. But by using B.xsd as the 
root document for namespaceB, you only need to update this one file to include 
D.xsd.
