-A ``DerivedProjectedCRS`` — a CRS derived from an existing ``ProjectedCRS`` base — must be
-registered directly in the ``derived_projected_crs`` table. The base CRS must already exist
-in the ``projected_crs`` table (e.g. an EPSG entry), and a deriving conversion must be
-registered separately. For example, to register a net projection derived from EPSG:32631

-    will produce a directed error pointing to the correct table.
