SRM_Ellipsoid_Of_Revolution
/*
 * REGISTERABLE ENUM: SRM_Ellipsoid_Of_Revolution
 *
 *   This data type specifies the list of
 *   1) reference ellipsoids of revolution and 2) spheres
 *   used in defining an Object Reference Model (ORM) within the
 *   Spatial Reference Model (SRM).
 *
 *   This list is taken from Tables C.2 and C.3 of the SRM, WD5.
 *   See the SRM for details on how the selection of a horizontal
 *   datum affects an ORM. See Table C.3 for the definitions of the
 *   semi-major axis and inverse flattening values for each of the
 *   listed ellipsoids of revolution, and table C.2 for the radii
 *   of the listed spheres.
