#71 Provide access to SOAP Fault element BizDoc

[prichards]

Build 6.0.0.254 (also 5.x)

It would be helpful to access the SOAP fault data returned when calling a web service that results in a SOAP Fault. In the case of an HTTP 500 result with a SOAP Fault retruned, $xavar:error_stack$ only returns the 500 message without additional detail:
"...Error in executing BizComponent [mysvc.xbc]: HTTP Post method error: 500 Internal Server Error at..."

However, in the XAware debug log, the entire contents (xml structure) of the <Soap:Fault> element is logged in the SEVERE error message.

This XML result should be made available to the BizDoc, so that appropriate action can be taken by the Error Handling for the sepcific error messages/codes contained in the SOAP Fault. Otherwise, all errors produced by the service can only be treated as "500 Internal Server Error".
