Well I was really asking what change you would like to see. There are
three paragraphs dealing with the lack of Accept-Encoding, are you pro-
posing to replace all of them by saying, if you can send it without any
encoding, then you must send it without any encoding if A-E is missing?
Or would you go even further and prohibit sending an encoded body even
if the server cannot send an unencoded body (you'd send 406 instead)?
