Description:
A UseCase specifies a set of actions performed by its subjects, which yields
an observable result that is of value for one or more Actors or other stakeholders
of each subject.

ClassifierIf true, the Classifier can only be instantiated by instantiating one of
its specializations. An abstract Classifier is intended to be used by other
Classifiers e.g., as the target of Associations or Generalizations.

Operations:
Signature: allIncludedUseCases() : UseCase;
Description: The query allIncludedUseCases() returns the transitive closure of all UseCases
(directly or indirectly) included by this UseCase.
Expression: result = (self.include.addition->union(self.include.addition->collect(uc | uc.allIncludedUseCases()))->asSet())
