Re: Review of draft-ietf-nsis-qspec-18.txt

Francois,
   
  In your "Proposed Resolution" posting to NSIS on 3 December http://www.ietf.org/mail-archive/web/nsis/current/msg08155.html you say:

  I saw no discussion of this proposed resolution on the NSIS list.  Who were the QSPEC co-authors who worked with you on the proposed resolution?

  OK.

  The above proposed paragraph is really unclear.  Which draft is setting up IANA Registries to assign Admission Priority parameters?  The way it reads it sounds like all three drafts are setting up registries but that somehow (magically) all refer "to the same Admission Priority".  How can that be if they assign different values?  Right now emergency-rsvp and nsis-qspec set up registries for Admission Priority and dime-qos-parameters is using the nsis-qspec registry as I recall.
   
  Please clarify the proposal as to which draft is setting up a registry for Admission Priority.  Also, please provide clearer proposed text to include in the drafts.  
   
  It would be good to see some discussion of the proposal on the list, to confirm and validate agreement of the WG.

  Hello,

For memory, the next rev of nsis-qspec is also expected to be aligned 
with the Resolution of the issue related to QoS Parameters encoding 
in , & . For 
convenience, I included below the recap on the corresponding 
resolution as announced on NSIS, DIME and TSVWG lists.

Just to make sure this does not fall through the cracks.

Cheers
