Thanks Sheng. For everyone's information, I am taking a few weeks unpaid leave so will not be as active on this list as I would have wished. We had some discussion back in January about different views of the requirements, which was left unresolved. See January 28 in the archive: http://www.ietf.org/mail-archive/web/grobj/current/maillist.html To fix that, it seems very important to get some real precision in the problem statement. Med, you sent some comments on draft-carpenter-grobj-reqts-00, maybe you can repeat for the list the high-level comments that affect the problem statement aspect?
