/**
    @short          protocol handler for "service:*" URLs
    @descr          It's a special dispatch/provider object which is registered for such URL pattern and will
                    be automatically used by the framework dispatch mechanism if such URL occurred.
                    His job is to create any registered uno components which must be coded inside
                    dispatched URL (may with some optional given parameters). After that such created
                    service must be hold his self alive. Such mechanism can be useful for UI components
                    (e.g. Dialogs, Wizards) only.
