*AD Section 5

[mnot]

*AD Section 5: FYI, a normative reference to RFC 5234 has been added because this document contains ABNF. See the IESG statement on "Guidelines for the Use of Formal Languages in IETF Specifications" (https://ietf.org/blog/guidelines-use-formal-languages-ietf-specifications/) - specifically "The use of a language requires a reference to the specification for that language. This reference is normative, and needs to fulfil the usual requirements for normative references (Section 7 of RFC 2026)." Please review where RFC 5234 is cited and let us know if you prefer otherwise.

Original:

   Priority is a Dictionary (Section 3.2 of [STRUCTURED-FIELDS]): 

Priority = sf-dictionary

Current:
Priority is a Dictionary (Section 3.2 of [STRUCTURED-FIELDS]).
The following is its ABNF [RFC5234]:

Priority = sf-dictionary

I think we can just remove the ABNF entirely as part of #1975, which would remove the need to ref rfc 5234

Fixed now
