I'm confused, the doc says:

"2.4 Fault Handling

During the operation of the Request MEP, the  participating SOAP nodes 
may generate SOAP faults.

If a SOAP fault is generated by the recieiving SOAP node  while it is 
in the "Receiving" state, the SOAP  fault is made available in 
http://www.w3.org/2003/05/soap/mep/OutboundMessage and the  state 
machine transitions to the "Fail" state."

Section " Receiving" allows for a SOAP message in the response 
HTTP entity body. Doesn't this allow a fault to come back over the http 
response like the WSDL robust-in-only MEP ?

An empty HTTP entity body, not an empty SOAP body - right ?
