Chris Abernethy: Adds a negative conformance test, that makes sure that if you try to issue a credential with a duplicate key, a 400 should be returned ✪
Mahmoud Alkhraishi: Actually passing this test is quite difficult as body-parser and most json parsing libraries end up silently dropping all duplicate terms excep tthe last one ✪
Chris Abernethy: That wasn't clear on the issue, maybe we should modify it to allow 400 or simply use last duplicate key ✪
