Section 1.1 says:
This specification uses the Augmented Backus-Naur Form (ABNF) notation of [RFC5234] and includes, by reference, the "token", "word", "OWS", and "BWS" rules and the #rule extension as defined within Sections 3.2.1 and 3.2.4 of [RFC7230]; as well as the "delta-seconds" rule defined in Section 8.1.3 of [RFC7231]
It should say:
This specification uses the Augmented Backus-Naur Form (ABNF) notation of [RFC5234] and includes rules, by reference, the "token" as defined in Sections 3.2.6 of [RFC7230], "OWS" and "BWS" as defined in Sections 3.2.3 of [RFC7230], and the #rule extension as defined in Sections 7 of [RFC7230]; as well as the "delta-seconds" rule defined in Section 8.1.3 of [RFC7231].
Notes:
Mapping of the keywords with the section numbers is incorrect. The correct mapping is as following:
"token" => Section 3.2.6 of RFC7320;
"word" => Not defined in RFC7320, but reported at Errata ID: 4439;
"OWS" and "BWS" => Section 3.2.3 of RFC7320;
"the #rule extension" => Section 7 of RFC7320;
