Do we even need the colorantIndex from the prtMarkerColorant table? Seems like unnecessary information that will never get used in this composite view of the two tables...
Same for Index - we implicitly already have it (1setOf is ordered) so why include it?
MaxCapacity should be REQUIRED since otherwise how do you interpret Level?
Finally, I would make at least the colorant Value conditionally required, otherwise the data can't be represented properly in UI.
