Section 2.1 has:

A client sends an HTTP request to a server in the form of a request message, beginning with a method (Section 7) and URI, followed by header fields containing request modifiers, client information, and representation metadata (Section 4), and finally a payload body (if any, Section 6.3.3).

A server responds to a client's request by sending one or more HTTP response messages, each beginning with a success or error code (Section 9), possibly followed by header fields containing server information, resource metadata, and representation metadata (Section 4), and finally a payload body (if any, Section 6.3.3).

So this is also specific to 1.1.

My proposal would be to define terms for request-line and status-line that are indenpendant of the protocol version.

For 1.1, these would map to what we had before (and might have to include the "Host" header field, right?).

For 2 (and 3, I guess), they would map to the pseudo header fields (all?).

We'd also have to fix the text above, as some ("Host") or all (pseudo header fields) are actually contained in the header field section.
