[39] [[XSL-FO]] は [[CSS]] もどきを独自定義していて、 [[TTML]] は [[XSL-FO]]
もどきを独自定義しているので、 [[TTML]] は [[CSS]] に似ている、
ということに [[TTML]] の中の人達ではなっているみたいですけど、
もどきは所詮もどきで、細かく見ていくと違うところがたくさんありまくる [SRC[>>35]]
んですよね。

[40] 指定方法もレイアウトモデルも違って、語彙と継承処理は若干似ているんだけど、
構文は違うし語彙も同じ意味で違う名前のものがちらほらあって、
「もどき」とはいっても「着想を得た」レベルでしか似てないというのが正直な感想かな。

[41] >>38 の [[TTML]] から [[CSS]] に変換するスクリプトの中の人は、
わりと簡単に変換できるし何が違うか言ってみろよwと主張しているけど [SRC[>>42]]
(そんなの最初に挙げた一覧 >>35 で十分わかるでしょう...)、
その変換スクリプト [SRC[>>38]] はけっこう複雑に見えるんですよねぇ。
これでそんなに違わないと言って良いのなら、
[[HTML]] と [[DocBook]] も簡単に変換できるから同じだとも言える。

[43] 両者違うのは問題だということになれば [[TTML]] を [[CSS]] と同等になるよう魔改造することになる
(そうすれば変換スクリプトも要らなくなるしよかったね!) けど [[L. David Baron]] ら [[CSS]]
側の人々は [[TTML]] と [[CSS]] は別物だからそれぞれでいいんじゃないかと言ってるし、
簡単に変換できるから現状で良いということなら誰もそれに異論は述べなそうだし、
[[TTML]] 側の人々が何を目指しているのかはよくわからないなあ。
