You should be... Must be that I can't remember seeing extra samples in
TIFF files, only a lot of colorimetri tags :-) The applications I work
with have a tendency to use more or less proprietary file formats when
dealing with extra layers...

Anyway, I still interpret the spec so that the section 20 tags apply
to RGB data (or data mapped to RGB) only, not to any extra samples.
