    3033== Proposed Solution ==
     34
     35A number of changes in FDO are proposed:
     36
     371) Add new FdoSpatialOperations_Relate to FdoSpatialOperations enumeration
     38
     392) Assign values to FdoSpatialOperations so they can be bitmapped:
     40
     41enum FdoSpatialOperations
     42{
     43    FdoSpatialOperations_EnvelopeIntersects = 0x0000,
     44    FdoSpatialOperations_Relate     = 0x0001, 
     45    FdoSpatialOperations_Contains   = 0x0002,
     46    FdoSpatialOperations_Crosses    = 0x0004,
     47    FdoSpatialOperations_Disjoint   = 0x0008,
     48    FdoSpatialOperations_Equals     = 0x0010,
     49    FdoSpatialOperations_Intersects = 0x0020,
     50    FdoSpatialOperations_Overlaps   = 0x0040,
     51    FdoSpatialOperations_Touches    = 0x0080,
     52    FdoSpatialOperations_Within     = 0x0100,
     53    FdoSpatialOperations_CoveredBy  = 0x0200,
     54    FdoSpatialOperations_Inside     = 0x0400
     55};
