You are very right that this must be made explicit.  I favour 1, though.

Actually there's a case to be made that servers should do 2 and 
consumers should do 1.  The party making the request can do nothing 
about the capabilities of the recipient, so has to beef up their request 
with everything that any receipient might want; the party making the 
reply knows enough to know what the client can accept, and so should 
only include a field if the client MUST accept it.

That's probably too complex though.  I favour 1.  Servers can be smart 
about what they send.

I favour this too, now.  I'll add it to the spec.  Where does it go?
