Bidirectional generalisation and nesting

[robH]

Currently EA will allow you to create Class B as a generalisation of Class A and Class A is a generalisation of Class B. Is this valid?

The same is also true for nested classes...

UML 2.0 Superstruct:

generalization
A taxonomic relationship between a more general classifier and a more specific classifier. Each instance of the
specific classifier is also an indirect instance of the general classifier. Thus, the specific classifier indirectly has
features of the more general classifier. See: inheritance.

And later in Associations

• generalization: Generalization

• Specifies the Generalization relationships for this Classifier. These Generalizations navigate

to more general classifiers in the generalization hierarchy. Subsets Element::
ownedElement.

My interpretation: not allowed.
