In Eclipse UML Ecore file, the Abstraction EClass contains an Ereference named mapping typed OpaqueExpression.
In omg uml specification the Meta class Abstraction contains an attribute mapping typed Expression.
OpaqueExpression in Eclipse UML API doesn't inherits from Expression. So I don't understand why OpaqueExpression is used.
Is it normal? Why this type has been chosen ?

There seems to be an inconsistency in the spec.
Figure 7.15 on page 35 of 07-020-05 indicates the type of 'mapping' to be
OpaqueExpression, whereas the text later on states it should be
"Expression".
