Colorset's `bitdepth` under https://docs.krita.org/en/untranslatable_pages/kpl_defintion.html#colorsetentry calls U8/U16 "unassigned" rather than "unsigned" integers. Less significant, but I'll mention it since it's in the same paragraph - the capitalization and spacing between integers and floating point values is different - "Unassigned 8bit integer" (no space before bit, no capitalization for integer) vs "16 bit Floating Point" (space before bit, all capitalized besides bit).
