Issue 17450: Multiple ownership not in UML semantic subset (smof-ftf)
Source: NIST (Mr. Conrad Bock, conrad.bock(at)nist.gov)
Nature: Revision
Severity: Critical
Summary: Section 10.1.1 (InstanceSpecification) has an operation getContainers with a postcondition returning potentially multiple instances linked at the owning end of composite associations.  This is disallowed under UML semantics, making SMOF not a subset of UML semantically.  Since SMOF is mainly concerned with multiple and dynamic classification, which does not affect issues of conflicting ownership (any more than multiple composite properties on a classifier do under the current MOF), it is not necessary for SMOF to address issues of ownership.
