参照；5-3 Character References、Character entity references in HTML 4
HTML4.01での文字実体参照は、W3CのSpecificationでは、Character entity references in HTML 4で扱われています。ここに少し手を加えて載録しておきますので、御利用下さい。
XHTML 1.1 における文字実体参照表もあります。何か変わってますかね？御利用ください。
キーボードから直接入力できない文字を入力する為に、文字参照と言う仕組みがあります。文字参照の方法は、番号とキーワードの 2 種類が使えます。昔は番号文字参照（&#番号;）のみだったようですが、今はキーワードで参照（&キーワード;）できます。
÷を参照するのに、文字実体参照÷の方が、番号文字参照÷よりも覚えやすいのは明らかでしょう。
【例】
| <!ENTITY | sect | CDATA | " § " | -- | section sign, | U+00A7 ISOnum | --> |
| <!ENTITY | 文字実体参照名 | データタイプ | "表示例 " | -- | コメント（補足的参考情報） | --> | |
文字実体参照名に注目してください。
上の例では、§ を参照する為には、§と書けば良い事が分かります。
因みに、ですが、このファイルでは、実際には文字実体参照ではなく、数字文字参照が使われています。
