Actually, the it was other way round (why do we care that BOBs are a concept).

Never mind, I need to offer a proposal.

In the initial draft, I think that the editors intentionally avoided defining the term "entity" as part of the vocabulary. I don't suggest defining that term, but having a means by which one would know that two Bobs are characterizations, possibly different, of the same entity, e.g., using an assertion like "sameEntity(bob1, bob2)".
