WSDL does provide enough information to invoke functions of any web-service. And the main benefit is that this is a standard, so that everybody who understands this standard knows how to call the functions. If you wanted to convey any specific information, then you can use the documentation tag for that purpose. > > For example, as far as I know it doesn't have any > formal mechanism for specifying constraints in order of > method invocation.

There is a more basic problem here.... Actually generally web-services architecture doesnt have a notion of session maintenance. so calling 'open' before 'action' sort of doesnt make sense in case of web-services.
