Response will be set to the body of the SOAP response message either as a stream or %XML.Node. If Response is a character stream, the body of the SOAP response will be written in the character set of the current locale.
If Response is "", then a new character stream will be created and assigned to Response.
If Response is an %XML.Node, then the %XML.Node will be set to point to the body DOM.

The Location property of %WebClient must be set to the endpoint of the web service before SendSOAPBody is called.
