5.4.2.1 ClassifierAlias
The ClassifierAlias association connects TypeAlias instances with the Classifier instances that they rename.

5.4.2.2 EnumerationLiterals Protected
The EnumerationLiterals association links enumeration literals to the Enumeration instances that contain them.
If the Enumeration’s isOrdered attribute is True, the ordering constraint on the association is relevant. Otherwise, it is
ignored.

Identifies the EnumerationLiteral instances relevant for a particular Enumeration instance. If the Enumeration’s isOrdered attribute is True, the ordering constraint on this association end can be used to determine a logical ordering for the EnumerationLiteral instances. Otherwise, ordering is ignored.class:multiplicity:aggregation: |

5.4.2.3 UnionDiscriminator
The UnionDiscriminator association connects a Union instance with the StructuralFeature instance that can be used to determine
which UnionMember instance is currently present in the Union instance. This “discriminating? attribute may be a feature of
the UnionMembers themselves or may be a feature of some Classifier that contains the Union instance as one of its Features.
In the former case, the discriminating feature will usually be present at the same offset in each UnionMember instance. If
the discriminator reference is empty for a particular Union instance, it is considered to be an “undiscriminated? Union and
determination of the current UnionMember residing in the Union is usage-defined.
