Neil,

The WS-Addressing WG discussed your email at [1] during last week's 
concall. Although this is not an official WG endorsed response, the WG 
asked me to respond to your email based on the discussions on the call.

The authors of the proposal confirmed that the reply had to have an 
empty HTTP entity body (and not empty SOAP body). It was a typo.


 >[2] Exceptional Cases - Sending Faults to the 'Wrong' Place

WS-Addressing does not change the SOAP processing model (when bound to 
SOAP). Processing of a SOAP message may result in fault(s) (such as a 
mustUnderstand fault). There is no requirement in the SOAP processing 
model as to where (and how) the faults are sent, if they are sent at 
all. SOAP distinguishes between "generating" a fault and "sending" a 
fault. The SOAP processing model talks only about generating a fault. 
Whether a generated fault is sent back to the sender of the message or 
not may depend on the underlying transport, underlying binding used, 
security considerations, application specific semantics, policies, MEPs etc.

A similar issue was discussed before [2] and the WG concluded that 
wsa:FaultTo applies only if the receiver can understand WS-A and can 
process the message/headers. The WG decided not to include anything in 
the spec to call this out, as this would be repeating what the SOAP 
specification already says.

Thanks and regards.

-Anish
