> It's hardly possible to extend org.apache.cxf.ws.security.policy.model.AlgorithmSuite
with a custom non-standad algorithms.
> The possible solution is to refactor org.apache.cxf.ws.security.policy.builders.AlgorithmSuiteBuilder
to get all algorithm suites using cxf extension mechanism, for example, 
> {code}
> public class AlgorithmSuiteBuilder implements AssertionBuilder<Element> {
>     private Bus bus;
>     public AlgorithmSuiteBuilder(Bus bus) {
>         this.bus = bus;
>     }
>     public Assertion build(Element element, AssertionBuilderFactory factory)
>         throws IllegalArgumentException {
>         SPConstants consts = SP11Constants.SP_NS.equals(element.getNamespaceURI())
>             ? SP11Constants.INSTANCE : SP12Constants.INSTANCE;
>         Element policyElem = DOMUtils.getFirstElement(element);
>         String algoSuiteName = DOMUtils.getFirstElement(policyElem).getLocalName();
>         AlgorithmSuiteLoader loader = bus.getExtension(AlgorithmSuiteLoader.class);
>         AlgorithmSuite suite = loader.getAlgorithmSuite(algoSuiteName, consts);
>         if(suite == null) {
>             throw new IllegalArgumentException("Algorithm suite \"" + algoSuiteName +
"\" is not registered");
>         }
>         return suite;
>     }
>     public QName[] getKnownElements() {
>         return new QName[]{SP11Constants.ALGORITHM_SUITE, SP12Constants.ALGORITHM_SUITE};
>     }
> }
> {code}
> {code}
> public interface AlgorithmSuiteLoader {
>     AlgorithmSuite getAlgorithmSuite(String localName, SPConstants consts);

> {code}
