The WwAcknowledgeableConditionType represents a stateful message event from a module and is formally defined in Table 40. It is used to classify conditions to recognize acknowledgeable and confirmable event messages with the extensions of the interface IWwEventMessageType. The 0:EnabledState of the linked condition is used to map the active state of an event message. The behavior corresponds to the description of the 0:AcknowledgeableConditionType defined in OPC UA Part 9.
