/// coordinate systems. The instances of a single ProjectedCoordinateSystem COM class can
/// be used to model different projected coordinate systems (e.g., UTM Zone 10, Albers)
/// by associating the ProjectedCoordinateSystem instances with Projection instances
/// belonging to different Projection COM classes (Transverse Mercator and Albers,
/// respectively).
