I also feel that a modified version of the RFC 2119 statement should be
defined and specified in a small RFC.

I like Dave's addition, but also think adding the word "only" is worth
doing:

      The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL
      NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED",  "MAY", and
      "OPTIONAL" in this document are to be interpreted as described in
      RFC 2119 only when capitalised.

Leaving out the "only" still leaves the statement (slightly) ambiguous;
it's the same as the difference between "if" and "if and only if".


I agree that's an improvement.

I think it's a significant improvement, despite my other comments. However,
we should also insert "NOT RECOMMENDED" (see the erratum #499 on 2119).
