@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.
