--
-- Specification Disparity Notes:
-- * ST_OrderingEquals(geometry, geometry) is implemented as per

-- (http://edndoc.esri.com/arcsde/9.1/sql_api/sqlapi3.htm#ST_OrderingEquals)
-- * Geometry constructors default to an SRID of -1, not 0 as per SQL/MM specs.
-- * Boolean return type methods (ie. ST_IsValid, ST_IsEmpty, ...)
-- * SQL/MM : RETURNS 1 if TRUE, 0 if (FALSE, NULL)
-- * ESRI in Informix : RETURNS 1 if (TRUE, NULL), 0 if FALSE
