<br>
According to the ISO 639 Joint Advisory Committee [1]:<br>
<br>
"A language code already in ISO 639-2 at the point of freezing ISO 639-1<br>
shall not later be added to ISO 639-1. This is to ensure consistency in<br>
usage over time, since users are directed in Internet applications to<br>
employ the alpha-3 code when an alpha-2 code for that language is not<br>
available."<br>
<br>
Even if such a code element were added to ISO 639-1, it would not be<br>
added to the IANA Language Subtag Registry. According to RFC 5646 [2]:<br>
<br>
"In order to avoid instability in the canonical form of tags, if a<br>
two-character code is added to ISO 639-1 for a language for which a<br>
three-character code was already included in either ISO 639-2 or ISO<br>
639-3, the two-character code MUST NOT be registered."<br>
<br>
and:<br>
<br>
"Codes assigned by ISO 639-1 that do not conflict with existing<br>
two-letter primary language subtags *and that have no corresponding<br>
three-letter primary defined in the registry* are entered into the IANA<br>
registry as new records of type 'language'." [emphasis added]<br>
