UML22 — UML2: Actor cannot have ownedAttributes

Constraint [1] in section 16.3.1 is incorrect.
[1] An actor can only have associations to use cases, components, and classes. Furthermore these associations must be binary.
self.ownedAttribute->forAll ( a |
(a.association->notEmpty()) implies
((a.association.memberEnd.size() = 2) and
(a.opposite.class.oclIsKindOf(UseCase) or
(a.opposite.class.oclIsKindOf(Class) and not a.opposite.class.oclIsKindOf(Behavior))))

An Actor is a BehavioredClassifier and therefore cannot have ownedAttributes. The constraint above would have to iterate over all the associations in the model and insure that if one ownedEnd is an Actor or UseCase, the other ownedEnd must be a UseCase or Actor respectively.

Agreed. This also resolves issues 13948 and 14875
