Doug, you are right. In reference to your following statements, I checked my
copies of 639-1 and 639-2, and I couldn't find any reference to the reserved
codes ('qa..qt' or any other range) in 639-1, whereas 639-2 has the reserved
codes as you stated.
Regards, Erkki
ISO 639-1, as stated earlier, has assigned 'qu' to Quechua. This is
reflected in the Registry. I don't have a copy of 639-1 and don't know
if it reserves 'qa..qt' or any other range. The 639-2 Web site, which
lists 639-1 allocations, doesn't mention any such reservation.
ISO 639-2 and 639-3 have defined 'qaa' through 'qtz' as "Reserved for
local use," which is reflected in the Registry as "Private use."
