Hi everyone,

First of all thank you for all the work done in this WS-DD TC. As a Web Services
and DPWS user, I am particularly happy that many little annoying things are now
disambiguated in DPWS. In particular several of these made our work very
difficult when we wrote the "DPWS for OSGi" specification in 2007 (OSGi RFP-86,
the RFC has not been made public).

Anyway, I was a bit surprised that the brand new SOAP-over-UDP specification
does not provide the only missing building block for using it easily in current
Web Service engines: the WSDL binding. Indeed WSDL-driven code generators are
widely used, and there is no doubt that standardising a WSDL binding would ease
implementation of the DPWS standard in most public engines - thus enforcing
interoperability.

I don't know for the C world, but on the java side, there are already examples
of "request for binding" that would solve quite a few interoperability issues
and improve the overall developper's experience. See e.g. JSON or JMS bindings
to name a few. One could argue that these transport protocols are a bit 'out of
scope' of the core web services intent. But it is definitely not the case for
SOAP-over-UDP, and DPWS proves that the need is real.

I hope that this TC will help building a simpler and easier-to-get web service
vision, for devices. Best regards.
