<definitions targetNamespace=
  "http://actioncon.com/contract/po" ...>
    ...
  <portType name="ptPurchaseOrder">
    <operation name="opSubmitOrder">
      <input message="tns:msgSubmitOrderRequest"
        wsam:Action="http://actioncon.com/action"/>
      <output message="tns:msgSubmitOrderResponse"/>
    </operation>
  </porType>

</definitions>

Example 19.13 - A WSDL operation contains an input element with the wsam:Action extensibility attribute. However this attribute is not added to the output element.


<soap:Header>
  ...
  <wsa:Action>
    http://actioncon.com/action
  </wsa:Action>
</soap:Header>

Example 19.14 - The populated wsa:Action header.


<soap:Header>
  ...
  <wsa:Action>
    http://actioncon.com/contract/po/
    ptPurchaseOrder/msgSubmitOrderResponse
  </wsa:Action>
</soap:Header>

Example 19.15 - The wsa:Action element value, auto-generated based on default rules that concatenate the WSDL target namespace value, port type name, and message name.
