But first, Listing 11 demonstrates the standard form that every WSDL file takes.

The WSDL file defines its own namespace. WSDL adds a targetNamespace attribute to the <definitions> element. The targetNamespace attribute may not use a relative URI. Conversely, it must use the fully qualified URL. The namespace allows the author to qualify references to entities contained within the WSDL document.
