The following rules describe the Ports element:

  • A port defines an individual endpoint by specifying a single address for a binding.
  • The name attribute provides a unique name among all ports defined in the enclosing WSDL document.
  • The binding attribute refers to the binding using the linking rules defined by WSDL.
  • Binding extensibility elements are used to specify the address information for the port.
  • A port must not specify more than one address.
  • A port must not specify any binding information other than address information.
