 // 20. "browser_version" is a VERSION structure (defined below).  If this

 // VERSION includes "op", "style", "number", and "number2".  "op" can be any of

 // is optional and can be "lexical" or "numerical"; if it's not specified, it
 // defaults to "numerical".  "number2" is only used if "op" is "between".

 // "number" is used for all "op" values except "any". "number" and "number2"
 // are in the format of x, x.x, x.x.x, etc.
 // Only "driver_version" supports lexical style if the format is major.minor;
 // in that case, major is still numerical, but minor is lexical.

 // STRING includes "op" and "value".  "op" can be any of the following values:
 // "contains", "beginwith", "endwith", "=".  "value" is a string.
