    Message Priority specifies the placement of the Message in the message queue. This placement determines when the actor will process the message.

    0Low—Specifies that the message will be processed after messages of all other priorities. Multiple low-priority messages are processed in the order they are sent.
    1Normal (Default)—Specifies that the message will be processed after critical- and high-priority messages but before low-priority ones. Multiple normal-priority messages are processed in the order they are sent.
