I've received some interesting replies on my earlier REST posting. It looks like Sam's even done better! Here's a question for everyone: Is this URL legal according to the SOAP spec? http://keithba.com/soap.xml

I think it matters to this discussion. In fact, even if SOAP precludes this, does it preclude using URIs to point to a specific SOAP-enabled resource in general? I don't think SOAP does. Imagine this logical name: soap://keithba.com/hitCounter and this action: soap://keithba.com/hitCounter/CurrentHits

I'm leaning towards thinking that there is in fact a URI name for any particular SOAP message, and that this is the action. (WS-Routing puts the action in the message. Assume we are talking about all WS-Routing or WS-Routing-like SOAP messages.)
