CORBA35 — [CCM] Interface Repository Metamodel

in the BaseIDL there is a class StructDef which has the Attribute members of
Type Field. How can I model a IDL struct with more than one entry?
I think there should be a aggregation from StructDef (1<>----->*) to the Field
class (Page 8-10 of the CCM Spec).

*) With EnumDef there is the same problem, I guess a assotiation from EnumDef to
string (1<>----->*) would solve it (Page 8-10 of the CCM Spec).

*) Also with ExceptionDif and its attribute members (Page 8-11 of the CCM Spec).
