This is a followup on my followup here.

After rapping some with Alex I was thinking about what an expression would look like on the wire, provided it has limited capabilities allowed such as

• F(G(K(x))) = y
• F(G( [K(x) {attribute}] )) = y where selector was evaluated as some XPath perhaps?

In addition, the "combinator" capability I feel would be required to be another WSDL that a service could support (yes let us not forget one endpoint can service many actions from many WSDLs thank you =P)

Anyone have any other ideas on what makes sense in a combinatorial fashion we'd like to see?

I've already started playing around with a simple IQueryProvider to support #1 today. If anything comes of if I'll be sure to post the code.
