    Description

      EPSG geodetic dataset version 10 and later uses a new SQL schema different than the one supported by Apache SIS until now. The new SQL schema aims to support dynamic datum. The EPSGDataAccess class needs to be adapter before we can support latest EPSG datasets.

      Things to revisit after this upgrade

      Search for all occurrences of "EPSG:5819" is source code. This is the CRS code for "EPSG topocentric example A". It should be a DerivedCRS, but EPSGDataAccess confuses it with a ProjectedCRS. The problem is that the COORD_REF_SYS_KIND column in EPSG database contains the "Projected" value even if, according EPSG guidance note, the operation method is classified in the "Coordinate Operations other than Map Projections" category.
