Hi,
I'm not sure I'm explaining my problem correctly so let's try this. I've created the elements (which of course is a simplified example) according to:

If I do it like that I get a section in the element properties pre-populated with my tags:

.
I want the tags (color in this case) to be predefined the same way also for the attributes I create on elements of MyElement-type but can't get that to work. My guess is that the MyElement does not use the MyAttribute-stereotype when creating attributes but rather the standard attribute metaclass. Basically my question is, how do I do this correctly?
Regarding the inheritance, I know that's not how inheritance is supposed to work but from a business-modeling perspective, when tagged values are used for metadata purposes, it would actually be quite convenient if all the tagged values on attributes got the same values as those on the element as sort-of a default setting. Anyway, I can managed without that functionality as long as I at least can get the tagged values also on the attributes.
Thanks for your patience
Edit: Actually, I just notice that it does indeed work if I create a toolbox-item for MyAttribute and from there drop a MyAttribute on a MyElement which confirms my suspicion above. So I guess my question now is, how do i get MyElement to always define attributes as MyAttribute no matter which way of adding attributes to an element I'm using?
