Remove this informative reference. Shorten the paragraph using this reference to Geography and geometry values are represented as geometry types as defined in [RFC7946] . , with the following modifications: Keys SHOULD be ordered with type first, then coordinates, then any other keys If the optional CRS object is present, it MUST be of type name, where the value of the name member of the contained properties object is an EPSG SRID legacy identifier, see [GeoJSON-2008] . Note: RFC7946 uses the World Geodetic System 1984 (WGS 84), which is a superset of the EPSG SRID 4326 that the CSDL specs define as the default SRID for Edm.Geography  types.
