FYI, though it doesn't seem to matter to this issue, there's an errata in 9.5;

http://skrb.org/ietf/http_errata.html#post

FWIW though, I don't think an entity should be required, because;

1) if a server/resource wants to interpret a message with no entity in
some particular way, it should be allowed to ("The actual function
performed by the POST method is determined by the server")
2) an HTTP message is self-descriptive with respect to message size,
so there should be no issue with actually sending POST messages with
no entity

It's a similar argument to the HTTP FAQ about why HTTP doesn't
preclude GET requests from including an entity.

Not quite sure what you mean by that.

I don't see any problem with that optional request envelopes.

Cheers,
