        If same implementation provides the service <type>ExportFilter</type> too,
        code must distinguish between filtering into a target document (for import) or
        filtering from a source document (for export). This can be recognized by saving
        state of used interfaces <type>XExporter</type> or <type>XImporter</type>!
