Hi Randy,
Yes, we agreed to add a TTL to the registration (consistent w/ notification
subscriptions,
etc.).
The Device-Keep-Alive operation was renamed Get-Notifications (to align w/
IPP).
The notifications *are* asynchronous from the Cloud Imaging Service to the
Proxy
(keep-alive, jobs-available, etc.). The in-band IPP Get-Notifications
mapping saves
introducing XMPP or some other notification transport.
Cheers,
- Ira
