/// systems. However, if two objects supporting this interface have the same dimension,
/// axes, units and datum then client code is permitted to assume that the two coordinate
/// systems are identical. This allows several datasets from a common source (e.g. a CAD
/// system) to be overlaid. In addition, some implementations of the Coordinate
/// Transformation (CT) package may have a mechanism for correlating local datums. (E.g.
/// from a database of transformations, which is created and maintained from real-world
/// measurements.)
