Issue 8883: UML 2.0 Super/Use Cases/Subject of a Use Case (uml2-rtf) Source: MID GmbH (Mr. Detlef Peters, d.peters(at)mid.de) Nature: Clarification Severity: Significant Summary: Section 16.3.2 allows "classifiers in general to own use cases". Section 16.3.6 however states that the "subject of a use case could be (...) any other element that may have behavior". These elements are called "BehavioredClassifier" by Section 13 and are a specialization of Classifier. Please clarify the consequences of these statements: - may all Classifiers be owners of UseCases, but only BehavioredClassifiers be the subject of a UseCase? - what is the semantics of Non-BehavioredClassifiers, e.g. an Interaction or OpaqueBehavior, owning a UseCase or being a subject of it? A UseCase "represents a declaration of an offered behavior" (16.3.6), so how can Non-BehavioredClassifiers ever offer a behavior?
