Consider a different terminology for whitespace that includes comments

[eugenesvk]

What often tripped me when translating v1 grammar to parsing instructions was the disconnect between whitespace that I understood as literal space that's... white (i.e., all the blanks) vs KDL's definition that includes various comments.
Same thing happened during updates to v2

             ↓ this is whitespace
ws := unicode-space | multi-line-comment
                          ↑ this isn't

Maybe this space + comment could use some other term like

• commentspace or comspace or cs or cws
