Unable to load schema which imports or includes partial schemas

           Summary: Unable to load schema which imports or includes partial
                    schemas
           Product: Xerces2-J
           Version: 2.2.0
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: XML Schema Structures
        AssignedTo: xerces-j-dev@xml.apache.org
        ReportedBy: d.g.van.der.laan@eccoo.rug.nl


[ First of all, we are using Xerces 2.2.1, but that version is not yet included 
in the version selection list. ]

It seems the new Xerces2 has different behavior concerning schemas which are 
build up by including partial (not valid as stand-alone) schemas. 

We are using a schema A, with target namespace NS1, which imports a schema B, 
with target namespace NS2 and includes a schema C, which also has target 
namespace NS1. Schema C uses elements from NS2, but does not include schema B. 
Therefore, schema C is not valid stand-alone, but schema A is. So:

A(NS1) ---> import B(NS2)
   |
   -------> include C(NS1), uses NS2


Using the schema validator of Xerces 1.4, this worked fine. Now we use Xerces 
2.2.1, latest build, but the validator keeps complaining schema C may not 
reference elements from namespace NS2.

If we import schema B into C, all works fine. But we want to reuse schema C 
with different versions of schema B (more or less strict schemas). So we have 
schemas A, A', A'', etcetera, importing schemas B, B', B'', etcetera, but which 
all include the same schema C.
