TDocStd_Application class extended to open/save a document of XmlOcaf and BinOcaf format from/to standard SEEKABLE stream object which should support SEEK functionality. Open and SaveAs DRAW commands got new additional argument "-stream" to turn on using of stream functionality. The main changes for BinOcaf format applied in: FSD_BinaryFile class (static method using standard stream added) BinLDrivers_DocumentRetrievalDriver and BinLDrivers_DocumentStorageDriver classes use standard stream object as an argument The main changes for XmlOcaf format applied in: LDOMParser and LDOM_XmlWriter classes use standard stream object as an argument Unused class FSD_Archive and its siblings removed from MFC samples.
