Section 1 says:

   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 [RFC2119].

It should say:

   The key words "MUST" and "MAY" in this document are to be
   interpreted as described in [RFC2119].

Notes:

Other than in the above-quoted sentence, there are no
instances of "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", SHOULD",
"SHOULD NOT", "RECOMMENDED", or "OPTIONAL" in the RFC (and the
instances above surely cannot be interpreted as described in RFC
2119; they are mere labels in the context of that sentence).
--VERIFIER NOTES--
The keyword paragraph is standard, and although words are mentioned that are later not used, this is not an error.
