Nature: Clarification
Severity: Significant
Summary: A UseCase is a BehavioredClassifier, which is a Classifier, which has features of Type Property (Subclasses are Operation and Reception). However "feature" is a derived union and neither BehavioredClassifier nor UseCase define subsets of it. Therefore the features of a UseCase are always an empty set. I heard of one UML-Tool that actually enforces this rule.
