MDG definition to restrict stereotyped attributes on a class?

[Guillaume]

Hi,

My UML profile has the TypeA stereotype on the Class metaclass, and Type1 + Type2 stereotypes on the Attribute metaclass.
I'd like to define that a "TypeA" stereotyped class can either have "Type1" or "Type2" stereotyped attributes.

Is there a way in the MDG Uml Profile definition to enforce this? For instance when one uses Enumeration classes, attributes are automatically stereotyped enum. Is there a way to achieve something similar?

The enum thing only happens when using Java as langauge, and I'm pretty sure it's a hardcoded thing.

Try defining a pair of <<metaconstraint>> as described in the help here: Define Metamodel Constraints. I think you will need a <<metaconstraint>> from Type1 to TypeA with umlRole=class, and the same from Type2 to TypeA.

EDIT: Or you may need to reverse these and have umlRole=ownedAttribute.

It looks exactly what I'm looking for but unfortunately I cannot get it to work.
I created metaconstraints from the class stereotypes to each attribute stereotype with umlRole = ownedAttribute
I also tried with the metaconstraint from the attribute stereotype to the class with umlRole = class

Any idea on what I might do wrongly?
