The closer you can go to what you need is to define 2 keys: a first one "Object" under "Repository" and the second one on "State" in the scope of "Object". This will do the job of checking that your values a uniques keys in their respective contexts, but you won't be able to reference the concatenation of the 2 keys. Hope this helps.
