Hello,
Relation :- Ident_ST "Has_type" Datatype
Cardinality :- (M : 1)
Optionality :- (M : M)
Relation : Datatype "Is_of_Identifier" Ident_ST
Cardinality :- (1 : M)
Optionality :- (M : O)
For 2nd relation, structtype can't have any identifier. So jst want
to create ((structtype) is Datatype). But it gives me error on validating at this step.
Is_of_Identifier must have some value.
Here Has_type & Is_of_Identifier is EReference & left as well right parts are Classes. For both references containment & container attributes are false. I also don't want to set Opposite.
Conceptually above both are different associations.

What does this notation correspond to in Ecore? Upper and lower bound I
suppose, but those have only a single value each.

What's structtype?

Can you describe what you have in Ecore so I'm not left wondering what
your notation maps to?
