Thanks - as I read your message, the references need to be:
- ISO 639, [DATE], and subsequent registrations and changes
for 2-letter codes
- An expected future extension of ISO 639 that introduces 3-letter
codes
There is still no work going on to introduce a notation for dialects
and sublanguages within a language code, which some have been
worried about.
There is a work going on to define some kind of control sequences to
indicate language within a text stream, but this is still some way
from completion, and should therefore not be referenced except as
"work in progress".
Is this a correct summation of your message?
It is *enormously* helpful to have your comments, Olle!
