 Recommendation: The defined_in relationship should be removed.  CorbaStruct should redefine the 
 has_feature relationship it inherits from FeatureOwner by adding a constraint saying that the relationship 
 can be populated only with CorbaStructMember instances.  CorbaStructMember should redefine the defines 
 relationship it inherits from Feature by adding a constraint saying that the relationship can be populated only
