My data is packed data (I have SampleValidRange, and scale/Offset values to
obtain the geophysic data).
(I have a different product having as validRange, -3.4028235E38,
3.4028235E38, then, I cannot use a validMin set to 1).

This is exactly what I have done. Indeed the 4.9E-324 value visualized while
debugging my category comes from having defined a NumberRange as you are
suggesting.
Is there a way to tell the CategoryList package private constructor checking
if the originating categories ranges are included or excluded, then build
the inverse GeophyisicCategoryList in compliance with this?
