When included in a message, this header provides a means for the sender to include an identity token (see [LibertySecMech])
that specifies an identity at the service that is the target of the message.
In the typical case that a WS-Addressing endpoint reference is used to address a message, the value of this header
block is taken from the <wsa:Address> of the EndpointReference.
