The actor Attribute
A SOAP message may travel from a sender to a receiver by passing different endpoints along the message path. However, not all parts of a SOAP message may be intended for the ultimate endpoint, instead, it may be intended for one or more of the endpoints on the message path.
The SOAP actor attribute is used to address the Header element to a specific endpoint.
