I was referring to draft-abarth-mime-sniff-01, not any of the httpbis
drafts. In the former there is for example "The user agent MAY wait for
512 or more bytes of the resource to be available." That could be 512
bytes before removing chunked transfer encoding, all transfer encodings,
the content encoding, etc. depending on which byte stream one believes
"resource" (or "representation" per Mark's suggestion) refers to.
