OSID - osid.ontology.OntologyNotificationSession Service Interface Definition

Interface	osid.ontology.OntologyNotificationSession
Implements	`osid.OsidSession`
Description	This session defines methods to receive notifications on adds/changes to `Ontology` objects. This session is intended for consumers needing to synchronize their state with this service without the use of polling. Notifications are cancelled when this session i
Method	canRegisterForOntologyNotifications
Description	Tests if this user can register for `Ontology` notifications. A return of true does not guarantee successful authorization. A return of false indicates that it is known all methods in this session will result in a `PERMISSION_DENIED.` This is intended as a hint to an application that may opt not to offer notification operations.
Return	`boolean`		`false` if notification methods are not authorized, `true` otherwise
