Explanation

WSDL (Web Services Description Language) is an XML-based language that describes web services' functionality, including available operations, message formats, and endpoint locations. It tells clients HOW to access a web service. SOAP is a messaging protocol, UDDI is a registry for publishing/discovering services, and WS-I is an interoperability organization - none of these describe the service interface like WSDL does.
