KERML_ — Navigability of AnnotatingElement<->Annotation meta-association

Annotation relationship creation modifies navigable AnnotatingElement::annotation property.

There is a navigable AnnotatingElement::annotation property, so it means AnnotatingElement is modified if Annotation is connected to it. KerML allows Annotation to be defined outside AnnotatingElement, for example AnnotatingElement can be owned in rootNamespace1, but Annotation connecting to that AnnotatingElement can be owned in rootNamespace2.

This causes exactly same problems with models serialization as UML had with NamedElement::clientDependency before making it derived.

If possible AnnotatingElement::annotation should be non-navigable or derived.
