In case I was not clear in my previous response, I propose we resolve this by reusing terminology already used in authoritative documents and standards, as opposed to what we, as individuals, might argue (at length) is most correct and proper. If the authors want to go a different direction, I'm fine with that; it's an editorial issue as far as I'm concerned.
