  32     Supported URLs must match follow format:
  33     <code><i>protocol scheme</i>:<i>protocol specific part</i></code>
  34     If a handler provides optional arguments ("?") or jump marks ("#") depends from his
  35     definition and implementation. The generic dispatch provider will use registered
  36     URL pattern to detect right handler.

  53         <p>
  54         Sometimes it can be useful for a handler object, to know something about the
  55         environment, in which it runs - especially the frame. For this case the generic
  56         code (which uses the handler) will ask for this optional interface and use it, if it exist.
  57         Following parameters are passed to the service:
  58         <ul>
  59         <li>sequence< any >[0] => the frame for which this ProtocolHandler was created [com.sun.star.frame.XFrame]</li>
  60         </ul>
  61         </p>
  62
  63         <p>
  64         Please note: if this mechanism is used it seems not useful (nor possible) to implement a ProtocolHandler
  65         as a singleton. Otherwise the implementation can't distinguish between different environments
  66         and her corresponding dispatch requests.
  67         </p>
