 *

 * <p>In principle, all sub-types of {@link CoordinateReferenceSystem} may take on the role of either source or

 * derived CRS with the exception of a {@link GeocentricCRS} and a {@link ProjectedCRS}. The latter is modelled

 * as an object class under its own name, rather than as a general derived CRS of type "projected".

 * This has been done to honour common practice, which acknowledges projected CRSs as one of the best known

 * types of coordinate reference systems.</p>

 *

 * Note: gvSIG derived these interfaces from GeoAPI in order to have a simpler API and also to

 * avoid namespace collisions (e.g. GeoAPI 3 vs GeoTools interfaces). There is no plans

 * to evolve these interfaces to adapt them to future GeoAPI versions.

     *   "<code>conversion</code>" may be confusing as a method name

     *   since it does not indicate which CRS is the source or which is the target.

     *   The OGC 01-009 specification used the <code>toBase()</code> method name.

     *   By analogy with 01-009, GeoAPI defines a method name which contains the "<code>FromBase</code>" expression.
