Even when the consumer supplied an entityInstanceKey, I'm unclear of how 
the producer can use it to uniquely associate data with an entity. What 
happens if two consumers supply the same entityInstanceKey (say, for 
producers not supporting registration)?

If I'm not mistaken, the same question applies here as well.
