> The relationship to spatialreference.org is one of being simply out-of-date. sr.org has not been updated in quite a while, and it needs a champion to come along and bring things forward.  sr.org gets its definitions from proj.4/GDAL as well as GeoTools. These have not been refreshed in at least a couple of years -- time for more than one EPSG database drop and the inclusion of datum shifting description in proj.4.

The better side of this is that once up to date these local coordinate systems do not change very much.
