XSDRedefinableComponent [message #76823]

Having a look into XSD.ecore in org.eclipse.xsd_2.4.1.v200808251517.jar,
I see that the abstract EClass "XSDRedefinableComponent" has the
abstract ESuperType "XSDRedefineContent".

All non abstract EClasses which have ESuperType
"XSDRedefinableComponent", e.g. "XSDAttributeGroupDefinition",
"XSDModelGroupDefinition", "XSDTypeDefinition" also have ESuperType
"XSDRedefineContent". The EClass "XSDRedefinableComponent" is never
inherited without also inherting "XSDRedefineContent".

So, the EClass "XSDRedefineContent" is inherited directly AND indirectly.

Is there any special reason for such a - I tend to say bad - modeling?
Will the direct inheritance be removed in later versions?

Regards,
Joachim Back

I suppose that making the diagrams pettier at the expense of redundant
inheritance in the model isn't an ideal trade-off. I'll have to add
redefineable component to the concrete containment diagram to make that
complete. When I convert to using Ecore Tools instead of Rose, I could
definitely do that. Please open a bugzilla enhancement request to track
the issue. Redoing the diagrams with Ecore Tools will be a lot of work
and isn't a priority mind you...
