The only "problem" with that is that config.language is not 100%
compatible with RFC 1766, which uses the ISO definitions of language.

In config.language we use TYPO3-internal 2-digit shortcuts. Most of them
match the ISO definition, but some don't.

For example Greek is "gr" in TYPO3, but "el" in ISO definition. See
$t3lib_cs::isoArray variable for a list of mismatches.

Maybe we could use this mapping table to translate them to ISO
corresponding, but there are some changes needed, for example "br"
should be "pt-BR", "ch" => "zh-CN" (in an lang attribute), etc. Maybe
add a second mapping for RFC-1766 conformance. Masi should know more
about it, as he is the language specialist. :)
