How to choose Key Identifier Type?

[Gabriel Millaire]

Hello,

I have been looking around for a way to choose the Key Identifier Type for 
signature using Axis2 Rampart.

I seem to only be able to find the "old" way of doing it, through 
OutflowSecurity:

<parameter name="OutflowSecurity">
        <action>
            <items>Timestamp Signature</items>
              <user>jack</user>
            <signaturePropFile>security.properties</signaturePropFile>
            <passwordCallbackClass>
               org.swview.test.axis2.client.PWCallbackHandler
            </passwordCallbackClass>
            <signatureKeyIdentifier>SKIKeyIdentifier</signatureKeyIdentifier>
            <signatureParts>
            </signatureParts>
        </action>
    </parameter>

What I am looking for is how to through the Policy in a WSDL file, or 
programmatically via RampartConfig or related means.

Does anyone have a clue how to do that?

Thanks,
Gabriel
