Support the specification of OCL constraints to limit the applicability of
stereotypes. For instance, let's say you want to specify that a stereotype can
only applied to instances of EClass if the instance of EClass is abstract.
This should be quite easy to implement. Basically, we would have to
1. add an attribute to Extension in the profile metamodel [1] that may hold an
OCL constraint; the OCL constraint should be specified in the context of the
extended metaclass
2. extend isApplicable(EObject, Extension, EList<Extension>) [2] in
StereotypeImpl by taking the evaluation of the respective extension's OCL
constraint on the specified EObject into account
