[[Ian Hickson]] としては[[後方互換性]]や[[要素の意味]]を重視しつつ[[メニュー]]と[[ツールバー]]の機能を統合的に提供できる
[CODE[menu]]
と[[命令]]の一連の機能群の中で [CODE[command]] という要素名が適切という認識でした。

[39] 
一方 [[Gecko]] は複雑ではない[[文脈メニュー]]機能の実装を求めており、
メニューの記述のための簡潔な[[要素]]があればよく、
統合的なモデルなどよりも機能を率直に表した[[要素名]]で十分と考えていました。
[[WebKit]] の開発者も (実装の意向は明言しないものの)
それに賛同しています [SRC[>>36]]。
