This wording is practically identical to the wording in rfc 2616. The same thing could happen in HTTP/1.1 if you only sent "identity;q=0" or "*;q=0". The error handling for the null case is mentioned in rfc 2616 section 14.3 right after rule number four. I was under the impression that the rules from http/1.1 still applied unless explicitly stated otherwise. Otherwise you basically have to copy the whole thing.

This is essentially option #2 I proposed earlier.
