 8    the constants mrds_db_model_info_VFILE_TYPE and DMFILE_TYPE. Changed version
 9    value to 2 from 1.

16 /* DESCRIPTION:
17 
18    This structure passes back information common to the whole database,
19    rather than that pertaining to a particular relation or attribute.
20    It refers to the database model, rather than to some submodel for that model.
21    This structure is to be used externally, not internal to MRDS.
