Events represent specific transient occurrences. Examples are system configuration changes and system errors. Servers expose the types of events they support in the Address Space. When an event occurs, the Server sends an event notification to subscribed Clients.
Each event type includes a set of attributes that define the information provided to Clients when an event occurs. These include among others the event id, time of occurrence, severity, and a message text. Clients select the fields they are interested in.

Usage Considerations
Receive unsolicited notifications of significant occurrences within the system represented by the Server.
Areas of interest include (but are not limited to); configuration change notifications, auditing of security or other changes, general purpose notification, safety limits of equipment, event detection, and abnormal situations.
