should be used for interaction to handle states of unknown filter during detection
If during loading time the filter can't be detected and wasn't given at calling time,
a possible ::com::sun::star::task::InteractionHandler will be used.
(it's a a part of used MediaDescriptor)
Such "NoSuchFilterRequest" will be used then to start right interaction on that to
get a decision wich filter should be used for given URL. A possible continiuation
of type XInteractionFilterSelect will transport this decision back to
generic filter detection and force using of it. Of course it's possible to abort
the loading process by use another continuation ::com::sun::star::task::XInteractionAbort.
