Format of .odb files is not a part of OpenDocument specifiaction. It's defined only by implementation of specific database backend (HSQL). I propose to rename the description so it will be just another database file format like others (e.g. sqlite, MS Access). I believe this will help everybody to notice difference between various database-related file formats.
