Mind the Gap
Paul Prescod wrote an excellent article on what's missing from web services. Essentially, what he describes in detail is what I expressed somewhat more succinctly in REST + SOAP as "REST - SOAP = XLink". I also commend his restraint from his normal tendency towards hyperbole - with one notable exception where he declares "the emperor has no clothes".
Overall, I endorse this article and the change to WSDL that Paul has been consistently championing (requirement R085).
