Explanation:
WSDL is often used in combination with SOAP and an XML Schema to provide Web
services over the Internet. A client program connecting to a Web service can read the WSDL
file to determine what operations are available on the server. Any special datatypes used are

embedded in the WSDL file in the form of XML Schema. The client can then use SOAP to
actually call one of the operations listed in the WSDL file using for example XML over HTTP.
