Remarks

This property is used only for Condition-Related Events (see EventType).

If the event notification is the result of a Refresh, the value of this property should be ignored.

It is server-specific whether this property will be True for a "new event". (A "new event" is any event resulting from the related condition leaving the Inactive and Acknowledged state.)
