A Web service's interface is covered in its WSDL format. A WSDL document always has a definitions element as its root. Any WSDL language element can contain the documentation element. The WSDL-specific elements are:

Types: Describes the types used by messages.
message: Defines the data passed from one point to another in a call.
portType: Defines a collection of operations.
operation: Defines a combination of input, output, and fault messages
input: A message that is sent to the server
output: A message that is sent to the client
fault: An error value returned as a result of a problem processing a message

binding: Describes the protocol being used to carry the Web service communication. Supported protocols are: SOAP, HTTP GET, HTTP POST, and MIME

service: Defines a collection of ports; each service should map to one portType and represent different ways of accessing the operations in that portType.
