Hi Thomas,
the attached XMI is not compliant. It contains the following incorrect 
fragments:

         <UML:StructuralFeature.type>
          <UML:Classifier>
           <UML:Namespace.ownedElement>
            <UML:DataType xmi.idref = 'G.7'/>
           </UML:Namespace.ownedElement>
          </UML:Classifier>
         </UML:StructuralFeature.type>

Correctly it should look as follows:

         <UML:StructuralFeature.type>
            <UML:DataType xmi.idref = 'G.7'/>
         </UML:StructuralFeature.type>

"Together" seems to produce an incorrect XMI.
Regards,
Martin
