Should the ABNF be this instead?
ABNF:
adsp-dkim-tag = %x64.6b.69.6d *WSP "=" *WSP
("unknown" / "all" / "discardable")[";"]
I ask just in case future updates or new new tags are added. I wish
to make sure the ADSP implementation do not fall trap to just checking
the entire string so that is all that is currently defined.
That's taken care of by the "tag-list" ABNF construction, as defined
in 4871. See section 4.3 of the ADSP document (particularly the
second paragraph).
