Dear WSCG,

The WS Description Working Group would like to request that you
coordinate the development of a SOAP one-way MEP, and the binding of
such a MEP to HTTP.

The WSDL 2.0 Adjuncts spec [1] defines one-way MEPs, yet our SOAP/HTTP
binding does not support such MEPs.  We believe out-of-the-box support
for one-way MEPs is an important use case, given impetus by
WS-Addressing's capability to separate requests and reply in time and
location.  Such interactions are likely to be modeled in WSDL as two
separate one-way operations, yet there is no standard binding of such a
MEP for SOAP over HTTP.
If such a MEP can be delivered prior to the completion of WSDL 2.0, we
would take a dependency on it.  Currently for in-out interactions we
default the binding to the SOAP Request-Response MEP [2].  We would like
to default the binding to the new SOAP One-Way MEP for in-only
interactions.  We don't however feel it is within our current charter to
define such a MEP.

We expect to forward a set of requirements for this MEP, developed in
the Async Task Force, to you shortly.

- Jonathan Marsh
on behalf of the WSDL WG
