Default Language
The AVF format allows you to set the default language code on attribute names.
By default, this parameter is set to en.
The parameter uses the list of languages provided by Apple, which can be found in /fme/install/plugins/avf/language_codes.csv.
Coordinate Precision (Maximum Number of Fractional Digits)
The writer will use the value of this parameter to limit the number of decimal digits printed for each coordinate.
Valid values range from 1 to 15. The default value is 7, which gives approximately 1-cm accuracy when writing WGS84 coordinates. A lower number of digits can dramatically reduce the size of the output file when writing out a large number of coordinates.
This parameter has no effect on attribute values that contain floating point numbers.
