UML14 — ElementOwnership

Summary: In UML versions 1.1, 1.2, and 1.3 the class diagram for the Core Backbone
declares ElementOwnership as an AssociationClass. This appears to be a
violation of MOF compliance, since the MOF meta-meta-model does not support
the notion of an AssociationClass.

Of course one could extrapolate AssociationClass from the MOF
meta-meta-model since it does support both Association and Class, and one
could also logically extrapolate a MOF-IDL and MOF-XML mapping for an
extrapolated MOF AssociationClass. However, two architects might
extrapolate these mappings in perfectly valid but different manners, since
there is no standard mapping for a MOF AssociationClass. Apparently such
an extrapolation has been performed in order to derive the IDL for the UML
meta-model that concerns ElementOwnership, but doing this without a
standard mapping seems dangerous.
