UML14 — isPolymorphic is never in a diagram

2.9.2.12 Reception has a attribute that states wheter an attribute is polymorphic or not (isPolymorphic);

2.5.4.3 Class has methods which can be polymorphic (isPolymorphic)

2.5.4.6 Interface has operations which can be polymorphic (isPolymorphic)

But there in the diagrams there is never an attribute called isPolymorphic, this should be corrected, i think the attribute isPolymorphic should be added to BehavioralFeature

This is a duplicate of issue 4617,
