I remain unconvinced that this is explaining more than confusing. I would like to hear from others what they think the figure means.

The use of non-ASCII labels in the DNS protocol is so confusing to many people, I am not sure that this is helpful.

If we keep the figure, that would be helpful, because they are *not* defined in RFC 1034 or 1035. If we are inventing new definitions, or changing existing ones, we might be better off just not showing this.
