From the endpoints view: The endpoint receives a message and returns a response. This is done through the type attribute, using a qualified name. binding, which specifies concrete protocol and data format specifications for the operations and messages defined by a particular portType. A element defines an individual endpoint by specifying a single address for a binding.

The port detail has two attributes: name and binding . Since WSDL documents can have many services and many ports inside each service, the service and port of the required endpoint has to be specified in the configuration via the service and port attributes respectively.

Each component refers to a previously defined component. The name attribute provides a unique name among all ports defined within the enclosing WSDL document. Now we are getting concrete by describing the transport protocol for the message exhange, the data format and give information about transport and coding of the messages. The name attribute provides a unique name among all bindings defined within in the enclosing WSDL document. port, which specifies an address for a binding, thus defining a single communication endpoint. The structure of WSDL is illustrated using a tree diagram. The operations that can be performed, and the messages that are involved.
