[Suit] Re: I-D Action: draft-ietf-suit-trust-domains-11.txt

[Deb Cooley <[e-mail]>]

This is soooo close.  Just a couple of things that need to be fixed.

Gorry, Gunter, Paul and Roman all made comments on this draft, and while it
appears that the authors have addressed most of their concerns, I don't see
replies to their comments.  In some cases, you may just be explaining what
something means, without a change to the draft.  For example, there are
some specific technologies used as examples - Arm TrustZone and Intel's
SGX, which may have been confusing to some.

(Gunter) Section 1, bullets:  There is a mix of first word
uppercase letters, and first word lowercase letters.  Pick one.  If you
choose uppercase letters, I suspect that a '.' at the end would be
appropriate.

(Gunter) Section 2:  Add Dependency Manifest and/or Dependent Manifest.

Section 2, second bullet:  Nit:  Mani/Manifest?

(Gunter with my spin) Section 3, last paragraph:  Your use of 'lockstep'
appears to be different than what I think of (two processors move from
instruction to instruction in 'lockstep').  Consider adding this to the
definitions, and I believe the process is described in Section 5.3 (at
least there is no occurrence of the word 'lockstep' in Section 5.4).

(Gorry) Section 5.6, table 1:  This would be better with a caption.
Something like 'added or modified commands'.

Section 10:  RFC 9124 should be Normative, no?

In general, the use of uppercase vice lowercase is confusing to me.  Enough
that I'm happy to leave it to the Editor to sort out.  Be prepared for
those questions....  Examples:  Software, Recipient, Components, Payload.

Let me know what the plan is.  We are currently in the I-D submission
blackout window, so when you are ready to push a new version, you will have
to send it to me and I'll send it to the Secretariat for publication.
[also, I leave on Wed, 16 July for Madrid, so it all gets more complicated
from that day.]
