>>21 ここに平成後期に再始動したこの仕様の改正の問題がすべて詰まっているといっていい。
この文書は[[国際化]]の専門家を称する人々の願望とそれに基づき[[Webブラウザー]]がどう動作するべきかが書かれているだけで、
世界の実態は考慮していないので、[[Webブラウザー事業者]]はこれを見ても何もできることはない。
[[Webブラウザー]]の仕事は現実世界のデータと慣習を処理することであって、
[[国際化]]の専門家を称する人々の思うあるべき姿の実現ではないので。


[23] 
まあ本来これが作られた時の世界観だと [[XML]] が世界の軸になって [[HTML]] や [[Webブラウザー]]のみならずいろいろな[[応用]]が作られて実装されていくはずで、
[[国際化]]の専門家を称する人々はそのいろいろな[[応用]]の設計者 ([[国際化]]に通じているとは限らない) が正しく[[国際化]]を実装できるとは限らないので、
特定の[[応用]]に限らず適用できる指針を示して導かないといけないという使命を帯びていたんだよね。
そんな世界は来なかったのはみなさん周知の通り。
