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.

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

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())
