Not clear whether server SHOULD or MUST send a response

[esko.dijk@…]

For unicast requests received by a server: Section 5.8.1 / 5.8.3 / 5.8.4 seem to state that a response SHOULD be sent by a server, or at least it can be read in this manner (I did). Section 5.8.2 (POST) seems to implicitly state that it MUST respond with something. Section 5.2 states "After receiving and interpreting a request, a server responds with a CoAP response" which seems to imply a MUST.
Is there a unified statement possible? E.g. for unicast requests a response MUST be generated, regardless of REST Method?

-> Make a pass through the document and make sure that the key word refers to the response code of the response being returned, not to whether a response is returned at all. Any volunteers?

I, at least, volunteer to do a pass through the document.
A possible next step is add a clarification text to section 5.2 saying that
"a server MUST respond with a CoAP response, apart from the exceptions stated
in section 8.2".

I know that in RFC 2616 also no 'MUST' language is used for a HTTP response,
but on the other hand HTTP does not have the multicast to confuse these
matters a bit.
