Nature: Uncategorized Issue
Severity: 
Summary: UseCase::extensionPoint subsets Classifier::feature, but ExtensionPoint is not a specialization of Feature.
Resolution: see above

Actions taken:
December 31, 2003: received issue
March 8, 2005: closed issue
Discussion: 
In Figure 401 (and in the corresponding diagram in the metamodel) in the
association end UseCase::extensionPoint, remove the “subsets feature”
specialization leaving only “subsets ownedMember”.
Also, on page 519, the corresponding description should be changed from:
?? extensionPoint: ExtensionPoint References the ExtensionPoints owned by the use case.
(Specializes Classifier.feature and Namespace.ownedMember.)
to:
?? extensionPoint: ExtensionPoint References the ExtensionPoints owned by the use case.
(Specializes Namespace.ownedMember.)
