Metaconstraints on Attribute stereotypes?

[Geert Bellekens]

Hi,

I'm doing a profile where I have a stereotype extending Attribute.
Now a was looking at the meta-constraint hoping to constraint the allowed type and owner for this stereotype.

I did the following

But neither one of these meta-constraints seem to do anything. I can add «SAP_alternativeKey» attributes to any type of element, and I can set any classifier as the type of my attribute, not only Classes.
Did I miss something?
Was I expecting too much?
What is the point of "umlrole=type" if not for attributes?

What is the point of "umlrole=type" if not for attributes?

It was originally used for a systems engineering language. ie. Preferring parts over attributes.

I would go as far as saying it should be extended to attributes.
