WSDL editing feature of this paragraph
How to introduce you to others what the Web service functionality, as well as the parameters of each function call it? You may write a document, you may even need to use words to tell people of your Web service. These informal methods have at least one serious problem: When programmers sit in front of computers you want to use your Web service time, their tools (such as Visual Studio) can not give them any help, because these tools do do not know your Web service. The solution is: reading machines can provide a formal description of the document. Web service Description Language (WSDL) is a XML-based language used to describe the Web service and its functions, parameters and return values​​. Because it is based on XML, WSDL is machine readable, but also human readable, it will be a great benefit. Some of the latest development tools, both according to your Web service WSDL document generation, and can import the WSDL document to generate the corresponding Web service calling code.
