    * add proper datum import and export support (being discussed on the mailing list)
    * fix the y-axis for projected CRS, because currently the driver (GDAL) expects top-down for projected crs but netCDF is bottom-up approach.  This issue need to be addressed for projected crs so that the resulting file in geotiff -> netcdf conversion (and vice versa netcdf -> geotiff) will not be upside-down when viewed in both gdal and netcdf software.

+ * add CF compliance checker to the autotests (issue #4233) - added in trunk, needs tests for projected CRS
  * support packed data (with add_offset and scale_factor) properly - I don't see where they are used, must be tested

 === Issues with the current implementation ===
  * The import process does not use the Conventions attribute and does not consider different possible Conventions (COARDS, CF-1.0, CF-1.5, etc.)
+ * netcdf history global attribute should be updated. Does GDAL offer a history mechanism?
+ * GDAL version should be recorded in a GDAL global attribute
+ * CF-version of file read could be kept in an internal variable, and default CF-version of output also
