The generic dispatch mechanism on a <a href="Frame.html">Frame</a>
search for such registered protocol handler and use it if it agrees with
the dispatched URL.

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

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