On the point of character set recommendations, I think what you should be=20
pointing at is not 1034 and 1035 in general, but say that they SHOULD=20
follow the recommendation of RFC 1035 section 2.3.1.
Since the rule was actually relaxed in RFC 1123 section 2.1, I think the=20
sentence should say "SHOULD follow the character set recommendation of RFC=20
1035 section 2.3.1, as modified by RFC 1123 section 2.1".
That's not an UTF-8 issue, but is a charset issue. The UTF-8 text is a=20
cop-out (I think), but it's appropriate to cop-out here; you're basically=20
saying "don't be surprised if people don't do what this spec recommends".
Does this make sense now?
