        *
        * <p>Typically, a server-side call will be made using a service
        * that is defined on the ServiceLocator.  These services will either be
        * remote calls onto Java Objects (RemoteObject), Web Service invocations
        * (WebService) or XML over HTTP/HTTPS (HTTPService) service calls.</p>
        *
        * <p>The results from these server calls will be handled by an object that has
        * been passed to the ServiceLocator as the designated "responder" (the
        * class willing to handle the response).</p>
        *
        * <p>Typically in the Cairngorm
        * architecture, the Responder interface is implemented by a concrete
        * implementation of a Command class that will use a BusinessDelegate
        * class to handle invocation of server-side business logic.</p>

           * within the concrete responder by using an appropriate cast.  For
           * instance, if you invoke a Java method that returns an AccountVO
           * value object, cast event.result to an AccountVO as follows:
           * <p>
           * <code> var customerAccount:AccountVO = AccountVO( event.result );</code>

           * by appropriate casting.
