Needs to handle uppercase too, so it should be strings.ToLower(s.Text()) or reDirective.FindSubmatch(bytes.ToLower(s.Bytes())) (and then cast string(m) and string(match[2]))

Or just change the regexp.

Add syntax directive for specifying the builder reference so that new dockerfile features can be targeted. New Dockerfile features can be added now without breaking backward compatibility or requiring users to upgrade. The base one would remain compatible with current moby/docker.
