Dear Shwetha Bhandari

Thank you for your review and comments.

There was a discussion at IETF 113 LAMPS meeting on CMP Updates style vs. RFC4210bis.
Please see the meeting minutes: https://datatracker.ietf.org/meeting/113/materials/minutes-113-lamps-01.pdf
As Russ points out in the shepherd writeup, the WG decided to go ahead with the CMP Updates document and provide a consolidated bis document in a later step.
Regarding RFC5912, CMP Updates only updates the ASN.1 module for CMP.
In detail it is like this, 
  - Section 2 and Appendix A.1 update RFC4210, 
  - Appendix A.2 updates RFC5912 Section 9, and 
  - Section 3 updates RFC6712.

Russ added this strategy also to the shepherd writeup:
   When this update was started, the number of updates was expected to
   be smaller.  It is recognized that complex update documents place a
   burden on implementers.  So, when LAMPS WG tries to progress CMP to
   Internet Standard, a bis document will be produced to combine the
   base specification and the updates.

CMP Updates introduces the general concept on how URI path segments may be used with CMP. As a concrete path segment CMP Updates defines the 'p'. For further path segments CMP Updates refers to Lightweight CMP Profile. It is planned to publish CMP Updates together Lightweight CMP Profile.

Russ stated in the shepherd writeup of Lightweight CMP Profile the following:
  There are four related Internet-Drafts that are coming to the IESG
  at roughly the same time.  Please publish all four at the same
  time with consecutive RFC numbers.  The documents are:
    1.  draft-ietf-lamps-cmp-updates
    2.  draft-ietf-lamps-cmp-algorithms
    3.  draft-ietf-lamps-lightweight-cmp-profile
    4.  draft-ietf-ace-cmpv2-coap-transport

I am not aware of additional documents covering such data models.


I hope, I sufficiently addressed your comments. If not or if you have further questions, please let me know.
