Hi all,

i've a problem in my metamodel, which i create by using the UML2 genmodel.
That work's fine, but now i have a technical or knowledge problem.

Is it possible to participate a derived subset???

I have a derived subset between two elements (exactly like the associations
between Package and Type in the UML2 spec (fig. 7-14)). Now, i have some
subclasses of Type, which i want directly be accesible from the Package.
Therefore i create a new association from Package to let's say TestComponent
(which is a Type), that subsets the /ownedType association end. But i didn't
know, how to implement the getOwnedTypes(). Actually, i use the
DerivedSubsetEObjectList, but there, if have no possibilities, to define the
participating subsets (like onwedTestComponent).
IMHO, i need something like DerivedSubsetSupersetEObjectList...

Thanks in advance.
