I don't think it's necessary to wait for any RFC or ISO document to approve the yi-hebr and yi-latn codes I've requested. The fact that there will be a future standard for script codes (which imputes meaning to the character-strings "hebr" and "latn") doesn't mean that these yi-hebr and yi-latn codes have to wait for that standard. -- Sean M.
