io.oss84.geotools:gt-epsg-wkt (maven):  EPSG and AUTO authority factories are defined for data.crs.CRSService. These codes are used to provide CoordinateRegerenceSystem for GCE and DataStore implementations that do not define their own native definition. Contains a Property file based CoordinateSystemAuthority (the property file is too large to be included in the main geotools release). This class will need to be ported to the new GeoAPI CoordinateReferenceSystem interfaces.
