Issue 18247: Profile: can a stereotype extend fewer metaclasses than another stereotype it specializes? (uml25-ftf) Source: NASA (Dr. Nicolas F. Rouquette, nicolas.f.rouquette(at)jpl.nasa.gov) Nature: Uncategorized Issue Severity: Summary: The UML 2.5 beta document is unclear about the combination of stereotype extensions & generalization relationships. Suppose a stereotype S1 extends metaclasses MC1 and MC2. Suppose another stereotype S2 specializes S1 and is only applicable to MC1 but not to MC2. Should S2's extension of MC1 then redefine S1's extensions of MC1 and of MC2 or is this restriction capability beyond the scope of the UML profile mechanism?
