Just beta-testing... :-)
What's really bad about any unqualified use of the word "environment"
is that it is already used in various IT-related contexts with varying
semantics. That's an invitation for misunderstandings.

For me, with the inclination to poke holes into everything, this
is BIG FUN :-). The list of valid values has an obvious tendency
to vary over time (we had a bunch of new ISO codes in the last few
years). I suppose nobody interprets this as mandating an online
connection to the authorities (ISO and IANA) so that, for example,
the string 'i-wurbl' would be checked whether it is valid to be
cast to xs:lang? But then, this would be cool web services to
provide! :-)

Neat idea. Though i hope having functionality for normalizing Unicode
strings and a TR10 collation framework built in is mandated or at least
recommended, as programming this in XSLT is, to reuse a recently used
phrase, 'no fun at all'.
