So the interpretation we are aiming for is option *a)*:
Each band is treated independently, and each one has its own NODATA
value. The NODATA value of one band is unrelated to that of the others.
That said, the question is whether this beh

Abel,
there is a subtelty:
a) If bands may have invalid pixels at different locations on different
bands, and that those bands have a different nodata value, then using
GDALRasterBand::SetNoDataValue() is the way to go.
b) If a given pixel is invalid only if its value on all bands matches

I am implementing a driver that allows different NODATA values for each band in
