  78         Sometimes it can be usefull for a handler object, to know something about the
  79         environment, in which it runs - especily the frame. For this case the generic
  80         code (which uses the handler) will ask for this optional interface and use it, if it exist.
  81         Following parameters are passed to the service:
  82         <ul>
  83         <li>sequence< any >[0] => the frame for which this ProtocolHandler was created [com.sun.star.frame.XFrame]</li>
  84         </ul>
  85         </p>
  86
  87         <p>
  88         Please note: if this mechanism is used it seams not usefull (nor possible) to implement a ProtocolHandler
  89         as a singleton. Otherwhise the implementation can't distinguish between different environments
  90         and her corresponding dispatch requests.
