Note that the companion standard, ISO , provides three -letter codes for languages — and for a vastly wider range of languages, at that. Online, however, we must stick with the two-letter codes.
At least, this is my interpretation. According to RFC , for languages with both a two-letter and a three-letter code, the two-letter code must be used. This also solves the problem of those languages that have two different three-letter codes, because all of them also have a two-letter code. The RFC request for comment mentioned in this citation merely refers back to ISO and tells us, in effect, that the only three-letter language codes we may use are those that do not have a two-language code.
But there are somewhat complex rules in place governing when a three-letter code may be coined without creating a corresponding two-letter code. From an accessibility perspective, this restriction will eventually have to be lifted.
Textual media are not the only kind available on the Web, and as more and more video becomes available, more and more sign languages will be available, and all sign-language names exist in the three-character specification under sgn.
It is technically impossible to specify a sign language on a Website as the standards currently exist. My recommendation? Using a code either 2, 3 or 4 letters long , rather than the name of a language, has many benefits as some cultures may have different names for the same language, while some languages may share the same, or similar, names even though they are unrelated.
The language codes are open lists that can be extended and refined. The job of maintaining these standards has been given to bodies known as Registration Authorities.
