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>

Please note: if this mechanism is used it seems 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.
