There is probably a small glitch in the grammar definition.

Technically it usually allows strings to be quoted or unquoted.

I always quote mine because otherwise some characters confuse the parser.

Personally if it were me who maintained the parser I would be very strict and never allow any unquoted values.

But I'm a bit radical about input validation because I work in InfoSec.
