+    @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 resettable continuation yet!
+                    Why? Normally 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 selected by handler to
+                    abort continuations... Retrying isn't very useful here... I think.
