    • MK: NXslit is for simple 2-blades slits, but NXaperture is for more complex geometries (to be used with NXoff_geometry as SHAPE)
    • PJ: whenever we want to deprecate or undeprecate something, it shall be extremely well explained why we do so
    • MK: undeprecate NXaperture and make the documentation clear, so it can be properly used.
