Just two types of notifications?

[openBackhaul]

Usual technology specific models are offering four types of notifications:

• ObjectCreationNotification
• ObjectDeletionNotification
• AttributeValueChangedNotification
• ProblemNotification

Because not object gets instantiated or deleted in the Alarms modelling there would be just two types of notifications, right?

• AttributeValueChangedNotification
• AlarmEventNotification

I would not expect to find Attribute Value Change Notifications in the information model for alarms (expect those related to alarm configuration, of course).

[openBackhaul]

In some sense, an alarm type object is created in the Capability section as soon as a user input (e.g. smoke detector) gets connected to the device, but it has not been found worth notifying this to the application layer.
Thus, no ObjectCreationNotification or ObjectDeletionNotification required.
