Well, sort of. But the general understanding was always that language 
information would belong to markup. These codepoints were only 
introduced because some people working on ACAP came up with an even 
weirder idea of how to encode language information, and a 
counterproposal was needed. When it was clear that neither ACAP nor the 
language tag codepoints were going anywhere, the language tag codepoints 
were deprecated (see http://tools.ietf.org/html/rfc6082).
