@jim_easterbrook I don't think B is a referrent of A if A encompasses other things? If A refers to B as C then B is a referent of C though. But I could be missing a nuance very easily.
@jim_easterbrook I think it's more likely the problem lies at this end. After the week I've had there's a strong possibility that's gibberish ;)
@bykimbo That's too much for this bear of little brain.
