Right, I was just about to mention that. I think we have a choice:

1) abandon use of this response code (and use a new response instead), e.g.

* CREATED "a123" "Denormalized name" MAILBOXID "123456"

  This would require clients to ignore an extra response, if they don't 
recognize it.

or

2) just describe limitations (e.g. no mailbox with "]" in it can have 
this response code) and make them a special case.

Hopefully will discuss this later today at the interim meeting.
