The EPSG database is proprietary and there is a legacy of confusion
around EPSG geographic coordinate systems. The OGC URN scheme fits Web
architecture, is non-proprietary, and designed to eliminate that
confusion. Carl Reed's IETF memo appears to be all but approved. Using
OGC CRS URNs is going to be the best practice in a few months. I believe
The GeoJSON spec should be forward-looking and recommend the best
identifiers for 2008-9-10, not the best identifiers for 2001.
