Error description

• When using WS Security (WS-Policy) sp:EncryptedElements
  assertion, DataPower might incorrectly apply the XPath
  expression. Below is a sample of the WS-Policy:
  
  <wsp:Policy wsu:Id="ec_policy">
    <wsp:ExactlyOne>
      <wsp:All>
     <sp:EncryptedElements
  xmlns:sp="http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200
  702">
  
  <sp:XPath>//*[local-name()='Body']//*[local-name()='data']</sp:X
  Path>
     </sp:EncryptedElements>
   </wsp:All>
    </wsp:ExactlyOne>
  </wsp:Policy>
  

Local fix

• A simple workaround is to omit the leading
  "//*[local-name()='Body']" in the XPath
  

Problem summary

• When using WS Security (WS-Policy) sp:EncryptedElements
  assertion, DataPower might incorrectly check for the required
  Encrypted Element when the XPath to identify the element
  contains "local-name()='Body'" used in conjunction
  with the Binding Assertion.
  

Problem conclusion

• Fixed in 5.0.0.10 and 6.0.0.2.
