Hi James,

a few comments:

- I think that using warn codes to provide feedback may be problematic; 
in particular the idea to encode data into the message, which in RFC2616 
is plain text. I think a new response header would be better.

- Finally: "Prefer" IMHO should go separate; in particular there are 
unresolved questions such as how are new Prefer codes registered. IANA?

Best regards, Julian
