What most people don't realize is that the WSDL a client uses and the WSDL that the provider use could be out-of-sync and everything will still work. If the client doesn't want to update, the service provider can just ensure that the 'old' XML is valid while creating a new WSDL. (ie optional fields etc) Minimizing change is a great concept, it just gets applied a the wrong level. Hi Arnold,
