Detailed Description

interface to filter documents

This interface will be used by service ImportFilter or ExportFilter to support loading/saving of documents in different formats. The target/source of such filter operations must be known before filtering will be started. (see XImporter and XExporter too) Otherwise this interface can't work right.
