The ID, WKT or Autodesk coordinate system xml representation of the coordinate reference system definition. The xml representation is the same format get via RealDWG's API - AcDbGeoData::coordinateSystem. Optionally, the string can be prefixed by the ID's namespace and a colon (:) where the following are supported: ADSK, EPSG. If no namespace has been specified, the ID is assumed to be a default Autodesk coordinate system identifier. If no definition exists with such a code and if it consists of numbers only, the ID string is considered an EPSG code.
Valid examples are:
- LL84 > Autodesk identifier (default)
- ADSK:LL84 > Autodesk identifier
- EPSG:4326 > EPSG identifier
- 4326 > EPSG identifier
- GEOGCS["WGS 84", DATUM["WGS_1984", SPHEROID[...]]] > WKT
