Hi Carsten,
yes, you are right about this! Thanks for pointing it out.
Indeed, the wording should be carefully selected, and I think in some
(most?) cases the token can be zero-length. However, as you correctly
state, this should not be a MUST. If the requester includes a token,
then the responder must conform to the CoAP specification.
Best,
Alexander

I would say that using zero-length token is possible. What I am not sure is
whether make it mandatory or not. I mean we could say that if the client sends
a zero-length token the server can consider it OK as per the text above. If
there is a non-zero length token value should be also fine.
There is never a reason to discuss token values -- these are chosen by
the requester based on its needs, and there is never a reason for a
responder to question that choice.
Grüße, Carsten
