You can save the Web service call composed by Stylus Studio. The file created when you save a Web service call includes the WSDL URL and the last Web service operation that you configured (including parameter values) prior to saving the file. For example, if you are using a Web service that provides separate operations for temperature conversions (one for Celsius to Fahrenheit and one for Fahrenheit to Celsius, for example), only the last one you test is saved.
