Hi Chris,

Your recent changes look good, and I think the description is sufficiently detailed.

Thank you very much,
Vlad

Hello Vlad,

A good point.

I have added wording to that effect:

  "this optional parameter is a list containing one or more items, separated by
   commas, with optional whitespace. Order in the list is not significant."

Does that sound okay or does it need more EBNF precision, like

  separator:  wsp* "," wsp*

The same wording occurs in several places: here are the exact commits
