Document The event header.

String Start date and time of the event, in the format yyyy-MM-dd'T'HH:mm:ss.SSSZ.

String Optional. End date and time of the event, in the format yyyy-MM-dd'T'HH:mm:ss.SSSZ. The absence of an End value in an event is often interpreted as indicating that the event started and ended at the same time. While this is valid in some consumers, other consumers consider it impossible for events to start and end at precisely the same time. When an event does not specify an End value, the consumer may set a default value, such as start time plus one millisecond.

String Optional. Indicates whether the event is a new event (Event) or a heartbeat event (Heartbeat). A heartbeat event indicates the temporal progress of the stream.

String The unique identifier of the event type. Event Types use qualified names (QNames) as the mechanism for concisely identifying the particular type. The value of evt:type combines the URI and local name as a string. For example, {http://namespaces.softwareag.com/EDA/WebM/Process/1.0}ProcessInstanceChange is the event type identifier that reports changes to a process instance.

String Optional. The version of the event type with which the event is compatible. An event should contain a version only if the event type supports versioning. An event should not specify a version if the event type does not support versioning.

String Optional. Unique identifier used to associate an event with other events.

String Optional. The unique identifier of the event. This element can be supplied by the user who emitted the event or can be system generated.

String Optional. The priority of the event to the producer. The value can be Normal or High.

String Optional. The identifier of the event producer. For example, this can be an application identifier or a globally unique identifier for each producer.

String Optional. The identifier of the user who emitted the event.

Document Optional. Custom header elements.

Document Optional. The event body.
