	Notifications are a key component of any topology data model.		Notifications are a key component of any topology data model.
	[YANG-PUSH] defines a subscription and push mechanism for YANG		[YANG-PUSH] and [RFC5277bis] define a subscription and push mechanism
	datastores. This mechanism currently allows the user to:		for YANG datastores. This mechanism currently allows the user to:
	- Subscribe notifications on a per client basis		- Subscribe notifications on a per client basis

	contents will be sent.		contents will be sent.
	- Specify either periodic or on-demand notifications.		- Specify either periodic or on-demand notifications.
	The authors would like to recommend the use of this mechanism for the
	TE-Topology notifications. They would also like to suggest the
	following extensions to [YANG-PUSH]
	- Specify specific entities that will trigger the push
	notifications. These entities can be specified by xpath, like the
	way a filter is specified.
	- Specify or limit the triggering event type, e.g. "add", "delete",
	"modify", or "all". The system sends the push notifications only
	when such events happen on the triggering entities.
	- Have an option to request either "incremental" or "full"
	notifications for an entity. For "incremental", the notification
	will contain only the changed attributes.
	5.12. Open Items
	- Coordinating changes to [YANG-PUSH]: The changes to [YANG-PUSH]
	discussed in Section 4.10 will need to be coordinated with the
	authors of that draft.
