I have a simple class diagram, with classes "Catalog" and "Category". I'll be adding many more classes, but these are the first two. There is a property of "Catalog" called "rootCategories", which should be a "Set<Category>". It's easy enough to define an association from Catalog to Category and label it on the source end with "rootCategories", but I'd like to define a "rootCategories" attribute of "Catalog" of type "Set<Category>".
I've created the two class icons, along with the association, but I don't understand the steps required to get that attribute created with that type.

David,
Your question appears to be about Java generics but that isn't directly
supported by UML itself. I suppose something equivalent is a
multi-valued property that's unordered and unique, but even this, if
mapped to Ecore and then to Java will result in EList<Category> not
Set<Category>...

Vlad,
I make no claims to be a credible UML expert let alone an expert in the
tools. I simply help as best I can when no one else steps in to do better.
Of course you copied my previous reply. It's a bit juvenile, but that
seems to keep you entertained.

David,
I believe in UML terminology it's just a many-valued (unbounded
multiplicity) property and that the fact it's a set, collection, or list
is implicit in things like the property being unordered and unique.
Unfortunately I know nothing about how to use the UML graphical editor
to achieve your, so I'm not sure what steps you need to take. Maybe
someone else will help with the specifics of your question.

Do we really need such an answer ? you undermine any shred of credibility you might still have left on UML modeling.
PS: Please don't say I copied your previous reply, I know and this intentional :)
