I think it's a good thing to have a common mechanism that could be 
reused by several authentication schemes (at least DIGEST and SCRAM for 

I find that the definition of the Authentication-Info header field is 
fuzzier in this draft than it was in DIGEST. In DIGEST this header field 
is intended to be used for "information regarding the successful 
authentication of a client response".
I'd tweak the wording in the draft to put back this precision. I think 
it would alleviate Martin's concerns. Or did I miss something?
