]REFS]
[HISTORY[
[32] [[Web Components]] の一部として単独の[[仕様書]]で開発が進められてきましたが、
基本的な部分が整い合意に達したとして、2016年4月、
[[HTML Standard]] に統合されました。(一部は [[DOM Standard]] に移されました。)
]HISTORY]
* 概念とプロトコル要素
[43] [[カスタム要素]]には、次の種別があります。
[FIG(middle list)[
- [[自律カスタム要素]]
- [[カスタム化組み込み要素]]
]FIG]
[36] その他次のような概念があります。
[FIG(short list)[
- [[カスタム要素]]
- [[妥当なカスタム要素名]]
- [[カスタム要素構築子]]
- [[カスタム要素定義]]
- [[要素の作成]]
- [F[カスタム要素状態]]
- [[カスタム要素反応]]
- [[カスタム要素反応群スタック]]
]FIG]
* 要素の[F[カスタム]]性
[34] [[要素]]は、[F[カスタム要素状態]]が [CODE[custom]] のとき、
[DFN[[F[[RUBYB[[[カスタム]]]@en[custom]]]]]]であるといいます [SRC[>>33]]。
[41] [DFN[[RUBYB[カスタム要素]@en[custom element]]]]は、
[F[カスタム]]である[[要素]]です。 [SRC[>>40]]
[42] 通常の[[要素]]とは違って、[[カスタム要素]]は、[[構築子][カスタム要素構築子]]や[[プロトタイプ]]を
([[利用者エージェント]]ではなく) [[著者]]が定義します。 [SRC[>>40]]
* 挿入手順群、削除手順群、属性変更手順群
[52] [[カスタム要素反応]]を参照。
* 歴史
[38] [[XBL]] 時代には、[[カスタム要素]]はありませんでした。
[[XHTML]] の世界観では、 [[XHTML]] の標準の[[語彙]]に対し、
独自の拡張は他の[[名前空間]]の[[要素]]や[[属性]]で指定することになっていましたから、
[[XML]] での利用を当初想定していた [[XBL]] も、
任意の[[名前空間]]の[[要素]]で事実上の[[カスタム要素]]を実現することを想定していたものと思われます。
;; この意味で、[[カスタム要素]]は [[XML名前空間]]の代替と言えるかもしれません。
[39] [[Web Components]] では、[[カスタム要素]]機能は、 [CITE[Custom Elements]]
[[仕様書]]として開発が進められました。いくつかの [[JavaScript]]
[[ライブラリー]]で本仕様に従ったもの、またはそれに近いものが実装された他、
[[Chrome]] でも実装が進められました。
;; [[Web Components]] も参照。

> JSON-LD and Web Components work really well together. The Custom Element functions as the presentation layer and the JSON-LD functions as the data layer that the custom element and search engines consume. This means you can build custom elements for any schema.org type, such as schema.org/Event and schema.org/LocalBusiness.
