Hi,

I would support the following actions:
  1) move configured notifications to another draft so dynamic subscriptions
      can move forward.
  2) make this draft NETCONF only and defer RESTCONF notifications
      until there is sufficient demand and consensus on how to do it.
  3) move all subscription monitoring to another draft or remove it.
       (The verbose notifications already define for subscription state
changes
        are sufficient).

I think this would leave the RPC operations and notification events, which
is all YANG Push should need to move forward. IMO a "binary push" transport
is more important than items 1 -3 above.


Andy
