Stereotyped relationship doesn't work across profiles

[Uffe]

I've got a profile A with a stereotype aaa, and a profile B with a stereotype bbb.
Profile A also contains a stereotyped dependency ddd.

I want to specify a stereotyped relationship for ddd from aaa to bbb. I drop bbb into profile A's diagram, draw the stereotyped relationship connector from aaa to bbb and specify ddd in the connector's stereotype tag. This doesn't work.

After saving the package as a profile, the profile contains
<UMLProfile profiletype="uml2">
    <Documentation id="bla" name="A" version="0.1" notes="This functionality hasn't been tested but let's dump it out there anyway"/>
    <Content><Stereotypes>
        <Stereotype name="aaa" ....>
            <stereotypedrelationships>
                <stereotypedrelationship stereotype="A::ddd" constraint="A::bbb"/>       <-- This should be "B::bbb"
            </stereotypedrelationships>
        </Stereotype>
    </Stereotypes></Content>
</UMLProfile>

So how do I specify a stereotyped connector between two element stereotypes which are in different profiles?

You have to create a new stereotype with the fully qualified name of "B::bbb"

This works exactly the same way as if you would be using existing stereotypes from ArchiMate or BPMN

Alright, thanks.

Not a word on the metamodel constraints page to point in this direction. Funny that.

The value of the tag 'stereotype' on the «stereotypedrelationship» connector can be either a simple or a fully qualified connector stereotype

Which describes how to reference the connector stereotype if that's in a different profile.

This is the target element stereotype. If you drop that actual stereotype element from its profile package into your diagram and draw the connector to that, it doesn't work. You have to create a fake stereotype element in the profile where you're defining the relationship, and then manually maintain that if the original stereotype ever changes. No help from the tool, and I repeat: nothing in the documentation to tell you that's what you need to do.
