SOAP is a simple XML-based protocol that enables applications to exchange information over HTTP.
Or more simply: SOAP is a protocol for accessing web services.

The optional SOAP Fault element indicates an error message.
If a Fault element is provided, it must be a child of the Body element. The Fault element may appear only once in a SOAP message.
