I added some code to check this, and it triggers on almost all
locales.  But I am afraid we need to allow more i18n years, as there
have been drafts out for several years, and all of them have used the
current year in the keyword content.

I guess this list should be ok:

  posix:1993
  posix:2002
  i18n:1999
  i18n:2000
  i18n:2001
  i18n:2002
  i18n:2003

Perhaps posix:* and i18n:* would be a safe choice for now?  The value
do not seem to be not used for anything at the moment.
