When using a default interface, are the WSDL and XSD files used by the SSE during the service execution or just for the workflow generation/compilation?
Regarding the service execution, the process is similar to that of a custom interface (see previous question). Regarding the compilation, the WSDL is the most important file although in practice you can look at the WSDL and the XSD as one single logical file since the former refers to the latter. The important information that is taken from the WSDL is the service name, the SOAP location to point to and the namespace. The XSL is not used for the workflow compilation.
