problem with xs:redefine pointing to file with xs:include

[in...@compchemcons.com]

Hi,

I am having a problem trying to transform an XML-Schema into a set of
Java classes.
My Schema uses the xs:redefine mechanism, i.e. it contains:

<xs:redefine schemaLocation="ODM1-2-1.xsd">  <!-- points to ODM1-2-1.xsd
-->	  	
    	<!-- we add an extra attribute to ItemData of ODM -->
      	<xs:attributeGroup name="ItemDataAttributeExtension">
      	<xs:attributeGroup  ref="ItemDataAttributeExtension"/>
          <xs:attribute ref="my:count" use="required"/>
      	</xs:attributeGroup>
      	<!-- we add an extra element to ItemData -->
      	<xs:group name="ItemDataElementExtension">
            <xs:sequence>
              <xs:group ref="ItemDataElementExtension"/>
              <xs:element ref="my:sub" minOccurs="1"
maxOccurs="unbounded"/>  
            </xs:sequence>
      </xs:group>  	
    </xs:redefine>

ODM1-2-1.xsd however contains (only) an xs:include pointing to the
foundation schema, i.e. ODM1-2-1.xsd has:

<xs:schema targetNamespace="http://www.cdisc.org/ns/odm/v1.2" 
           xmlns="http://www.cdisc.org/ns/odm/v1.2"
           xmlns:xs="http://www.w3.org/2001/XMLSchema"
           xmlns:ds="http://www.w3.org/2000/09/xmldsig#"
           elementFormDefault="qualified"
attributeFormDefault="unqualified">
    <!--
          import ODM foundation schemas
      -->
    <xs:import namespace="http://www.w3.org/XML/1998/namespace"
schemaLocation="xml.xsd"/>
    <xs:import namespace="http://www.w3.org/2000/09/xmldsig#"  
schemaLocation="xmldsig-core-schema.xsd"/>
	<xs:include schemaLocation="ODM1-2-1-foundation.xsd"/> 
</xs:schema>

and the ODM1-2-1-foundation.xsd then really contains the foundation
schema.

When I try to compile, I get the error:
C:\XMLBeans_ODM_VendorExtensions\schemas\my_simple-extension.xsd:13:
error: Redefined attribute group ItemDataAttributeExtension not found
in ODM1-2-1.xsd
C:\XMLBeans_ODM_VendorExtensions\schemas\my_simple-extension.xsd:19:
error: Redefined model group ItemDataElementExtension not found in
ODM1-2-1.xsd

Essentially this is correct: attribute group ItemDataAttributeExtension 
and model group ItemDataElementExtension reside in the to-be-included
file ODM1-2-1-foundation.xsd, but XMLBeans seems not to have included
the latter in ODM1-2-1.xsd.

How can I tell XMLBeans to do so ? 
Is this a bug, or not supported yet, or should I give a parameter.
I tried using as well using the ant build as using scomp.

Many thanks in advance,

Jozef
