the standard had already been released. What's the point of having standard language abbreviations if they're subject to change? "Annex B" in ISO 639-1:2001 (over a decade later, if that's a year) says "The changes were publicised, but they have not been included in printed versions of ISO 639." The first google hit for ISO-639 still makes no mention of these changes (http://www.w3.org/WAI/ER/IG/ert/iso639.htm). That rules. Remove "XS?"; as far as I can tell that's just an error in the "native language" page.
