Subject: [ISOJAC] ISO 3166 and re-use of identifiers
Dear JAC members,

concrete example is the re-use of CS (previously Czechoslovakia, now Serbia
The development of ISO 3166 is obviously outside the scope of the JAC.
However, since there are normative references to ISO 3166 in ISO 639, it may

"just" as individual experts).
I am not sure of the size of the problem in this particular case, but there

Political changes do make that necessary. It is the re-use that is the
If there is consensus in the JAC, I would suggest that we formulate a
comment to the effect that re-use of identifiers should be avoided since
such re-use causes problems and confusion for applications using ISO 639.
(Which are the only problems that the JAC needs to be concerned about.)
