I agree that such functionality would indeed be useful for validating
constraints that are defined in a standard metamodel. We plan to use the
Papyrus environment as a basis for diagram editors in MST... have you
proposed this as an inclusion in Papyrus and/or compared/contrasted it with
plans that team has regarding OCL?
