Hi,
We want to define a flags variable defining like that:
var:flag_masks = 3, 3, 3, 3, 12, 12, 12, 12 ;
var:flag_values = 0, 1, 2, 3, 0, 4, 8, 12 ;
var:flag_meanings = "very_bad_quality bad_quality good_quality very_good_quality
very_bad_weather bad_weather good_weather very_good_weather" ;
I understand from
http://cfconventions.org/Conformance/conformance.html that it is not allowed to use several time the same value (here zero) in flag_values:
Requirements:
* The flag_values attribute values must be mutually exclusive among the set of flag_values attribute values defined for that variable.
So it means that for each new "bits combination" in the flags definition we lost one of the combination because we cannot use zero more than one time?
Do you confirm this? What is the reason?
Thanks in advance,
Julien
