Backward XBF Storage Compatibility
Starting from OCC 6.7.0 the BinLDrivers were upgraded to version 7. What makes impossible to open the new files with the older versions of OCC (6.6.0 for example). Is there a way to force the storage driver to write the file in another version? (version 6)

The application that uses old OCC should be patched then.
