    @short          declaration of special continuation for filter selection
    @descr          Sometimes filter detection during loading document failed. Then we need a possibility
                    to ask user for his decision. These continuation transport selected filter by user to
                    code user of interaction.

    @attention      This implementation could be used one times only. We don't support a resetable continuation yet!
                    Why? Normaly interaction should show a filter selection dialog and ask user for his decision.
                    He can select any filter - then instances of these class will be called by handler ... or user
                    close dialog without any selection. Then another continuation should be slected by handler to
                    abort continuations ... Retrying isn't very usefull here ... I think.
