Agreed with all your responses. 2.4e is clarified. I think I am mistaken concerning the PKI DN data. The PKI DN is the distinguished name (x509 standard) of an identity (string). I was suggesting that we might need to make bindings of software/drivers to certain machine identities, not just classes of machine types. To do this, we will need some way to work with the security folks to use x509 identities to target software to them (or a unique id that is bound to the DN). I was just suggesting that perhaps some type of identity data will need to be stored/bound. Although, the right place for that is still probably in the job description/constraints, and has already been handled?
Pete.

Hi Pete,
Thanks. You gave me good points in your comments.

I got your point. Yes, it literally contradicts. I should have said:
[1.1-a] AAF/ARI: Application contents must be bundled in a single and
consistent archive, either in a actual contents or in an external reference.
This would be more specific rather than introducing the term "logical",
since it is used everywhere in the world and we haven't had its meaning
narrowed down here.

I believe the short description in the requirements text lacks restrictive
word to talk about the protocol. I should have said:
[2.4-e] ARI: ACS should allow ARI implementers to select a communication
protocol for transport of the bulk data transfer.
Doesn't it clarify the point yet?

Yes, I would like to cover diversity of the application contents; it includes
OS, drivers and middleware. What is "PK DN descriptors" here you mentioned?

Yes, I believe the above describes what I meant for.

I would call for expertise from the broader range of the people for this
discussion. Maybe we can attract them at the GGF13 sessions.
P.S.
Should we have some tele-conferences in February? We need decide the
session plan by Feb. 18 according to the GGF office notice.
