Anne, feel free to send to the list - we should capture this, it's
good stuff.

Good point.  This is a really tricky space, as you've got to account for
the different ways in which WSDL can interact with what its bound too.
Currently, WSDL has some issues when bound to application protocols[1],
but it's much more at home when bound to SOAP and MIME.  For example, the
current WSDL HTTP binding only supports tunneling, not the chameleon use
of SOAP.

So IMO, we should talk about how the connector semantics of Web services
using HTTP are replaced by those described in the WSDL, rather than
reusing those provided by HTTP (or of any underlying application
protocol).  (perhaps using those words)

How does that sound?
