Actually it doesn't; you can combine any of the 400-odd 639-1/639-2 language codes with any of the 200-odd 3166-1 country codes. The existing opportunities for nonsense are already immense, if that's where you want to go. However, in practice people who use silly tags like nv-dk (Danish Navajo) hurt only themselves, as no one will have any process to do anything useful with nv-dk content. > The closest equivalents involve protocols with a small set of > options that are presumed to be orthogonal.

That could already be done with the 80,000 existing possibilities under RFC 3066. -- John Cowan www.ccil.org/~cowan www.reutershealth.com jcowan@xxxxxxxxxxxxxxxxx [T]here is a Darwinian explanation for the refusal to accept Darwin. Given the very pessimistic conclusions about moral purpose to which his theory drives us, and given the importance of a sense of moral purpose in helping us cope with life, a refusal to believe Darwin's theory may have important survival value. --Ian Johnston _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
