Issue 18756: UML 2.5: Clarification of semantics for CreateLinkAction and DestroyLinkAction (uml25-ftf)
Source: Microsoft (Mr. Steve Cook, stcook(at)microsoft.com)
Nature: Uncategorized Issue
Severity: 
Summary: Semantics for DestroyLinkAction, and possibly CreateLinkAction, need clarification for the case of hybrid associations, i.e. associations which mix unique and non-unique ends.  For example, what does DestroyLinkAction do for the case of a unique end where one or more other ends are non-unique and there is more than one outgoing link for the same value at the unique end?
