i figured someone would ask for that eventually :).  it's not clear to
me how many valid values there are because the ISO 14652 standard is
difficult to obtain.  i've only be able to find 1999 and 2002 copies,
but i'm pretty sure there's other revisions as well.  maybe we start
off only accepting these two values and worry about the rest later ?

the other aspect is that, while we might validate some sanity on the
category fields in general, the code (afaict) is not structured for
actually handling the differences.  for example, if the locale says
posix:1993 or i18n:1999 (which the older ISO 14652 1999 standard
allows), we don't change the parsing behavior to reject features
that are new to i18n:2002.

i guess one thing at a time: let's update localdef to only accept
these two values and reject all others.  i'll look at that before
merging this patch in case it's easy to do.
