Is a draft really needed?

In RFC 5536, I for instance read wording about taking into accounts errata:

2.3.  MIME Conformance

    User agents MUST meet the definition of MIME conformance in [RFC2049]
    and MUST also support [RFC2231].  This level of MIME conformance
    provides support for internationalization and multimedia in message
    bodies [RFC2045], [RFC2046], and [RFC2231], and support for
    internationalization of header fields [RFC2047] and [RFC2231].  Note
    that [Errata] currently exist for [RFC2045], [RFC2046], [RFC2047] and
    [RFC2231].

    [Errata]       "RFC Editor Errata",
                   <http://www.rfc-editor.org/errata.php>.



Maybe *this* document could have similar wording, like "it extends 
news-fields defined in Section 3 of [RFC5536] amended with verified 
erratum xxx".


Also note that, when referencing RFCs, the current RFC Editor's practice 
is to link to <http://www.rfc-editor.org/info/rfc5536> (that provides a 
link to the errata page).



Last but not least, for *this* document, if extending the ABNF grammar 
of another RFC gives too much bargain, then why just *not* extend 
anything and just define <cancel-lock> and <cancel-key> as-is?

Definition of Jabber-ID or DKIM-Signature header fields for instance do 
not extend anything from RFC 5322 (mail):
   https://tools.ietf.org/html/rfc7259
   https://tools.ietf.org/html/rfc6376
