Dear JAC members and alternates,

The proposed change list for ISO 639 part 3 has had two or three proposed languages listed that involve splitting ancient languages. John Zagas of the Library of Congress and I discussed this last year, and agree that using the "macrolanguage" system would enable a split of the current part 2 language into two varieties in part 3. Thus, Ancient Greek [grc] would have one code for part 2 but two "Ancient Greek (individual language)" and "Medieval Greek" under part 3. Also, "Sanskrit" [san] would be split into "Sanskrit" and "Vedic Sanskrit" in part 3.

I would like to know if any of the Committee see a problem with this. I would like to process these requests in this cycle if possible, or else withdraw them as ill-conceived.

Thank you for any help you can provide on this question.
