<service name="svPurchaseOrder">
  <!-- Insert Policy Expression Here -->
  <port name="purchaseOrder-http-soap11"
    binding="tns:bdPO-SOAP11HTTP">
    <soap11:address location=
      "http://actioncon.com/services/soap11/po"/>
  </port>
</service>

Example 10.22 - A policy expression attached to the service policy subject is located directly beneath the opening service element.


<binding name="bdPO-SOAP12HTTP" type="ptPurchaseOrder">
  <!-- Insert Policy Expression Here -->
  <soap12bind:binding style="document"
    transport="http://schemas.xmlsoap.org/soap/http"/>
  <operation name="opSubmitOrder">
    ...
  </operation>
  ...
</binding>

Example 10.23 - A policy expression attached to the endpoint policy subject via the positioning of the policy expression beneath the opening binding element.


<operation name="opSubmitOrder">
  <!-- Insert Policy Expression Here -->
  <soap12bind:operation
    soapAction="http://action.com/submitOrder/request"
    soapActionRequired="true" required="true"/>
  <input>
    <soap12bind:body use="literal"/>
  </input>
  <output>
    <soap12bind:body use="literal"/>
  </output>
</operation>

Example 10.24 - A policy expression attached to the operation policy subject by placing the policy expression code under the opening operation element.


<input>
  <!-- Insert Policy Expression Here -->
  <soap12bind:body use="literal"/>
</input>

Example 10.25 - A policy assertion attached to the message policy subject by locating the policy statement beneath the opening input element.


<wsp:Policy>
  <wsp:PolicyReference URI="#reliability-policy"/>
  <wsam:Addressing><wsp:Policy/></wsam:Addressing>
</wsp:Policy>

<wsp:Policy wsu:Id="reliability-policy">
  <wsrmp:RMAssertion><wsp:Policy/></wsrmp:RMAssertion>
</wsp:Policy>

Example 10.26 - The wsp:PolicyReference element performing an include of another policy expression.

    <wsrmp:RMAssertion optional="true"/>
  </wsp:Policy>
  <wsp:Policy wsu:Id="security-policy">
    ...
  </wsp:Policy>
</definitions>

Example 10.27 - Two policy assertions located inline within a WSDL definition.


<binding name="bdPO-SOAP12HTTP" type="tns:ptPurchaseOrder">
  <wsp:PolicyReference URI="#composite-policy"/>
  <soap12bind:binding style="document"
    transport="http://schemas.xmlsoap.org/soap/http"/>
  <operation name="opSubmitOrder">
    <soap12bind:operation
      soapAction="http://action.com/submitOrder/request"
      soapActionRequired="true" required="true"/>
    <input>
      <soap12bind:body use="literal"/>
    </input>
    <output>
      <soap12bind:body use="literal"/>
    </output>
  </operation>
  ...
</binding>

Example 10.28 - The wsp:PolicyReference element used to pull in the "composite-policy" policy expression.
