[gdal-dev] Add coded field domains to file geodatabase

[Even Rouault]

Adam,

I've just clarified the doc to explain that it is read-only for the 
FileGDB driver.

The FileGDB SDK itself seems to have support for writing too, but this 
isn't implemented in the driver currently. Left as an exercise to the 
contributor as one says.
