UAF13 — Alignment of UAF::*Method with IsCapableToPerform

IsCapableToPerform (ICOP) connects client UML::Classes to supplier UML::Activities. This is the same purpose as UML::Operation, through featuringClassifier and method. While UAF::OperationalMethod, ServiceMethod and ResourceMethod exist, their link to IsCapableToPerform is apparent but absent. Recommend adding ICOP as an extention of not just Abstraction, but also Operation with additional caveats that it can only be applied as a stereotype when the Method is not Empty. An alternate strategy is to add a Tag to ICOP that points to the UAF::*Method that implements it, kind of like the SysML::AdjunctProperty.. Or the reverse, create a tag on UAF::*Method that points to it’s ICOP.
