Explicit actions

The following WSDL 1.1 fragment represents a booking system that contains explicitly defined <wsa:Action> properties:

<definitions targetNamespace="http://example.ibm.com/namespace" ...>
   ...
   <portType name="bookingSystem">
      <operation name="makeBooking">
         <input message="tns:makeBooking"
            wsa:Action="http://example.ibm.com/namespace/makeBooking"
         </input>
         <output message="tns:bookingResponse"
             wsa:Action="http://example.ibm.com/namespace/bookingResponse"
         </output>
      </operation>
   </portType>
   ...
</definitions>  

In this example, the input action of the makeBooking operation is explicitly defined as http://example.ibm.com/namespace/makeBooking, and the output action is explicitly defined as http://example.ibm.com/namespace/bookingResponse.

The following WSDL 2.0 fragment represents a booking system that contains explicitly defined <wsa:Action> properties:

<description targetNamespace="http://example.ibm.com/namespace" ...>
  ...
  <interface name="bookingInterface">
    <operation name="makeBooking" pattern="http://www.w3.org/ns/wsdl/in-out">
      <input element="tns:makeBooking" messageLabel="In"
            wsa:Action="http://example.ibm.com/namespace/makeBooking"/>
      <output element="tns:makeBookingResponse" messageLabel="Out"
            wsa:Action="http://example.ibm.com/namespace/makeBookingResponse"/>
    </operation>
  </interface>
  ...
</description>

In this example, the input action of the makeBooking operation is explicitly defined as http://example.ibm.com/namespace/makeBooking, and the output action is defined as http://example.ibm.com/namespace/makeBookingResponse.
