== Overview ==

This RFC is for adding spatial operator combinations support.

== Motivation ==

Allows implementation of the RELATE spatial filter.

[TODO]

== Proposed Solution ==

A number of changes in FDO are proposed:

1) Add new FdoSpatialOperations_Relate to FdoSpatialOperations enumeration

2) Assign values to FdoSpatialOperations so they can be bitmapped:

enum FdoSpatialOperations
{
    FdoSpatialOperations_EnvelopeIntersects = 0x0000, 
    FdoSpatialOperations_Relate     = 0x0001,  
    FdoSpatialOperations_Contains   = 0x0002,
    FdoSpatialOperations_Crosses    = 0x0004, 
    FdoSpatialOperations_Disjoint   = 0x0008,
    FdoSpatialOperations_Equals     = 0x0010,
    FdoSpatialOperations_Intersects = 0x0020,
    FdoSpatialOperations_Overlaps   = 0x0040,
    FdoSpatialOperations_Touches    = 0x0080,
    FdoSpatialOperations_Within     = 0x0100,
    FdoSpatialOperations_CoveredBy  = 0x0200, 
    FdoSpatialOperations_Inside     = 0x0400
};
