Julien,
That's fine. The conformance document probably needs a better statement
of the requirement when flag masks are used.
Grace and peace,
Jim

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
<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
