What are the elements of WSDL?

An WSDL document describes a web service. A WSDL document has a definitions element that contains the other five elements, types, message, portType, binding and service. The following sections describe the features of the generated client code:

types defines the (XML Schema) data types used by the web service.

message defines the data elements for each operation.

portType describes the operations that can be performed and the messages involved.

binding defines the protocol and data format for each port type.

service specifies the port address of the binding. The service is a collection of network endpoints or ports.

operation provides an abstract description of the action supported by the service.
