[news.eclipse.modeling.mdt.uml2] uml2.ecore mistake

[Cyril Faucher <cfaucher@xxxxxxxx>]

Hi,

I have a question about the metamodel of uml2: uml2.ecore.
The EClass "Element" has 2 EReferences "owner" and "ownedElement".
These 2 EReferences are derived.
My problem is: why they are opposite, I guess that comes from the 
translation of an UML Association in Ecore.

For me, I think that does not make sense in Ecore to have 2 derived 
EReferences and opposite.

Best regards,
Cyril.
