Issue 18945: extensibility (ifml-ftf)
Source: WebRatio Inc (Dr. Marco Brambilla, marco.brambilla(at)webratio.com)
Nature: Revision
Severity: Minor
Summary: Extensibility of the language should be made more explicit. The set of extensible concepts should be listed.
Resolution: 
Revised Text: The following text has been added at the end of Section 7.3:

Extensions are meant to refine the semantics of the core concepts or to provide specific cases of core concepts. As such, they must therefore refine the semantics of the IFML concepts, and not modify it. The following concepts (and their extensions) can be extended in IFML while still achieving compliance to the standard:
•	ViewContainer
•	ViewComponent
•	ViewComponentPart
•	Event
•	DomainConcept and FeatureConcept
•	BehaviorConcept and BehavioralFeatureConcept
Extensions of other elements are not allowed.
