Hi Mark! i think this is closely related to issue 6 "Message Property Optionality": http://www.w3.org/2002/ws/addr/wd-issues/#i006 AIUI you'd like an addressing xxTo: value to map to an populate a transport xxTo: value, whereas Marc is suggesting that a missing addressing xxTo: could default to to a value derrived from the transport. i guess both issues raise an issue with the way the spec is structured given that the SOAP and WSDL bindings are thus far "transport-neutral".

It does this by requiring that a wsa:Address EII map to the wsa:To SOAP header, rather than providing for the possibility of mapping to the identifier in the underlying protocol. The spec says; "The [address] property in the endpoint reference is copied in the [destination] message information property. The infoset representation of the [destination] property becomes a header block in the SOAP message." As an example of the problem, consider the following EPR (an edited version of one from the spec); <wsa:EndpointReference xmlns:wsa="..." xmlns:fabrikam="..."> <wsa:Address>foobar@fabrikam123.example</wsa:Address> <wsa:ReferenceProperties> <fabrikam:CustomerKey>123456789</fabrikam:CustomerKey> </wsa:ReferenceProperties> <wsa:ReferenceParameters> <fabrikam:ShoppingCart>ABCDEFG</fabrikam:ShoppingCart> </wsa:ReferenceParameters> </wsa:EndpointReference> Here, "foobar@fabrikam123.example" is required to go in the SOAP header, rather than in the "RCPT TO" command of the SMTP protocol (as an example of one email delivery protocol). I think the shortcoming will significantly hamper the ability for WS-Addressing enabled agents and services to integrate with existing applications on the Internet, such as email, instant messaging, and the Web.
