Hi Randy,
The practice recommended for SeaDataNet is to specify a fill value for the flag that is defined in the flag convention as 'missing value'. I always feel more comfortable with explicit semantics.
Cheers, Roy.

Subject: [CF-metadata] Quality flag values for missing data
What is the ?generally accepted? approach for how a specific quality flag value should be assigned for a corresponding data value (in the corresponding data variable) that has a _FillValue ?
Is it sufficient that, because the data variable value is _FillValue, the corresponding quality flag value can be undefined ?
