[62] [DFN[[[Web IDL]]]] は、 [[DOM]] その他の [[API]] の記述に使われる言語です。
仕様書としての [[Web IDL]] には、その言語自体の定義に加え、
[[Web IDL]] の記述と [[JavaScript]] の処理との対応関係や、
[[Web]] における [[JavaScript]] の [[API]] として実装するべき機能が規定されています。
* 仕様書

* JavaScript 束縛
[63] [[DOM API]] は [[Web IDL]] によって定義されていて、 [[Web IDL]] と [[JavaScript]]
の対応関係は [[Web IDL]] 仕様書で定義されています。
[64] いくつかの機能は [[Web IDL]] だけで記述できず、直接 [[JavaScript]]
の概念を参照して定義されています。

[CODE(DOMi)@en[[[WindowProxy]]]] になります。 [SRC[[[HTML Standard]]]]

- [68] [CODE(JS)@en[[[document.all]]]] ([CODE(DOMi)@en[[[HTMLAllCollection]]]])
は特殊な動作をします。
]FIG]
* 互換性
[59] 記述言語としての [[Web IDL]] は不特定多数の[[著者]]が直接使う機能ではないので、
しばしば非互換変更が行われます。通常の [[Web]] 技術とは違って、
必要の無い機能は積極的に削除されます。
[60] [[Web IDL]] の改訂と [[Web IDL]] を使う各仕様の改訂は、必ずしも同期していません。
[[Web IDL]] に追加される見込みの (または追加してほしいと希望している)
機能が各仕様で使われることもあります。各仕様でまだ使われている機能が [[Web IDL]]
から削除されることもあります。
* 歴史
** W3C DOM 時代
[69] [[W3C DOM]] は [[OMG IDL]] を使っていました。各仕様書には[[附属書]]として
[[Java束縛]]および[[ECMAScript束縛]]が規定されていましたが、
特に後者は曖昧でほとんど意味をなさないものでした。
** HTML5
[70] [[WF2]], [[WA1]], [[XBL2]] といった初期 [[WHATWG]] 世代の仕様書では、
一部例外的な機能について、 [[JavaScript]] でどのように実装するべきかの規定を含んでいました。
しかし [[IDL]] と [[JavaScript]] との基本的な対応関係が規定されていない以上、
曖昧なものとならざるを得ませんでした。 [[Ian Hickson]] は、
いずれそれを明確化する必要があると予定していました。
