[DDI-SRG] [CDI] new Canonical XMI after model transform

[Flavio Rizzolo]

A couple of other issues:

- The "refine" association seems to have a unique name now, even in the 
non-unique names xmi. For instance, Concept "refines" IndividualMember. 
Instead, we have Concept "Concept_refines_IndividualMember" 
IndividualMember.

- Identifier appears in all classes in the inheritance chains. For 
instance, Activity has Identifier, and so does Step, which is an 
extension of Activity. However, only the top non-abstract class in any 
inheritance chain should have Identifiable.

- Which brings me to the next issue: abstract classes should not be 
identifiable, should they? They are never instantiated, so it seems 
pointless they hay an identifier.
