So some small comments:
1) A nit in Change controller field for all the header fields: you
should either change it to IESG (iesg@xxxxxxxx) or IETF with subsequent
address ietf@xxxxxxxx.
2) Also, it might be useful to point out in the sub-sections of Section
3 which ABNF productions do the header fields match.
3) Section 4:
Terms not defined here are taken from [RFC5322] and [RFC2156].
You probably missed RFC 5234 (with e. g. <DQUOTE>) here.
Some ABNF nits:
4)
military-string = 1*69( ps-char )
No harm to change it to "1*69ps-char"
5)
std-precedence = "deferred" / "routine" / "priority" /
"immediate" / "flash" / "override"
std-message-type = "exercise" / "operation" / "project" / "drill"
Is there an ability to extend the allowed range of parameters here?
6)
nonneg-integer = "0" / (NZ-DIGIT *DIGIT)
Should this be
nonneg-integer = "0" / ( [ "+" ] NZ-DIGIT *DIGIT)
as non-negative integer implies that it may be prepended by "+" (as well
as zero - I don't know exactly).
7)
military-string-sequence = military-string
[ [FWS] ";" [FWS] military-string-sequence ]
I think
military-string-sequence = military-string
[ [FWS] ";" [FWS] military-string ]
is just the same but improves readability (unless you make this
intentionally, but I see no reason).
8)
Subject-Indicator-Codes = "MMHS-Subject-Indicator-Codes:"
[FWS] [sic-sequence] [FWS] CRLF
Can the header field appear to be:
MMHS-Subject-Indicator-Codes:
as you allow. Maybe removing [] around sic-sequence?
9) I'd like you hereby disallowed further registration of header fields
beginning with "MMHS", likewise RFC 5504 "Downgraded" prefix
(http://tools.ietf.org/html/rfc5504#page-18).
