ClassifierSpecifies each feature defined in the classifier. Note that there may be
members of the Classifier that are of the type Feature but are not included
in this association, e.g. inherited features.

ElementConstraints:
Signature: must_have_name() : Boolean;
Description: An actor must have a name.
Expression: name->notEmpty()
Signature: associations() : Boolean;
Description: An actor can only have associations to use cases, components and classes.
Furthermore these associations must be binary.
The OCL used here is not normative.Editor's notes: Actor.ownedAttribute is not defined.
Expression: true
Original: 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))))
Operations:
No additional operations.
