Thanks Julian. I just took a look at HTTPbis docs.

So, the WebSocket spec points RFC 2616 but uses ones in HTTPbis? I think
it's not friendly for readers. What's the plan for final publish? Will the
reference be replaced with HTTPbis?

e.g. I'm fine with keeping "WSP" instead of "LWS" as HTTPbis defines, but
one cannot find "WSP" in RFC 2616 referred from the sentence.

OK. But if you do so, I'd suggest that we clarify what *-Client and *-Server
means or remove those suffixes since the context (talking about S->C or
C->S) is clear (separated into two paragraphs). It's clear if they were
embedded in main text like Sec-WebSocket-Accept ABNF in the section
5.2.2.-3.-4. But they're not referred from any sentence but just appears
suddenly in the section 5.3. It's confusing. Sounds like header names are
Foo-Client and Bar-Server.

Thanks,
Takeshi
