Nl is not “*non-arabic numbers*” and it is not “*numbers that have a value by themselves*”. While both seem like correct statements, they are the wrong way to think about the Nl category. If either were entirely correct then there wouldn't be a need for No (Number other).
*Nl (Number letter)* is for *“Numerals composed of letters or letterlike symbols (e.g., Roman numerals)”* (copied from https://en.wikipedia.org/wiki/Template:General_Category_(Unicode) ) Note that Roman numerals also “*have a positional value*” and can “*be collated to other numbers to form bigger numbers*”.
