Hi Alex,

I think you are right when you say: For I guessed multiple stereotypes for 
metaclasses are only possible if you make an extension for each one?
The Element.isStereotypeApplicable(), is implemented that way and I also 
confirmed this by playing around with the UML editor.

You are correct in creating a required stereotype by setting the lower bound 
of the extension end to 1.  Extension::isRequired() checks the lower bound 
of the first owned end.

So I'm not sure why you can succesfully apply the second stereotype as you 
mention.

Can you post a small piece of your profile and model so I can see what 
exactly is going on.

Cheers,
- James.
