A.1 MathML用のDOCTYPE宣言

MathML 文書は、XML DTD for MathML を用いて validate されるべきで、これについては下の 第A.6節「MathMLのDTD」 でも示しています。

この DTD を用いた文書は、doctype 宣言を次の形で含むべきです:

<!DOCTYPE math 
    PUBLIC "-//W3C//DTD MathML 2.0//EN"
           "http://www.w3.org/TR/MathML2/dtd/mathml2.dtd"
>

URIは、必要に応じて ローカルにコピーされた DTD に変えることができます。

名前空間の接頭辞を用いるなら、文書要素は、以下のようになるでしょう:

<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML">
...
</mml:math>

また、接頭辞はローカルのDTDのサブセットとして以下のように宣言されなければなりません:

<!DOCTYPE mml:math 
    PUBLIC "-//W3C//DTD MathML 2.0//EN"
           "http://www.w3.org/TR/MathML2/dtd/mathml2.dtd" [
    <!ENTITY % MATHML.prefixed "INCLUDE">
    <!ENTITY % MATHML.prefix "mml">
]>

名前空間の接頭辞を制御のためにこのようにパラメータ実体の利用することは、 [Modularization] による指定の互換性を保つためです。

A.2 DTD モジュールとしてのMathML

しかし、通常 MathML 式は、完全な XML 文書を構成しません。 MathML はより大きなマークアップ言語の数学部分として用いられることを前提にしているためです。 特にMathML は、[Modularization] で定義されている モジュール として、XHTML系のマークアップ言語で記述された文書中で用いられるために設計されています。 便利のために XHTML DTD, extended with this MathML module バージョンも具体的な例として提供しています。 このバージョンは、一つのファイルの中に必要とされる宣言をすべて含めたものであり、完全な宣言などのためにいくつものファイルを参照する MathML DTD スタンドアローン版と比較できます。 このDTDを用いるためには、文書は以下の doctype 宣言を記述するべきです:

<!DOCTYPE html
    PUBLIC "-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN"
           "http://www.w3.org/TR/MathML2/dtd/xhtml-math11-f.dtd"
>

上でも述べたように、URIは変わることがありますので、DTDはローカルのコピーに帰ることができます。XHTML と MathML に用いられる名前空間の接頭辞は、パラメータ実体によって制御することができます。

A.3 名前空間の接頭辞の宣言

上でも述べたように、[Modularization] で説明されている、名前空間の接頭辞を MathML 要素名に提供するメカニズムを利用することが必要ないし便利であるときがあります。 下の DTD は、こうした利用方法ができるように設計されています。 もし DOCTYPE 宣言のローカルなサブセットとして、もしくはMathML DTD を含む DTD ファイルの中で、MATHML.prefixed というパラメータ実体が以下のように INCLUDE されるよう宣言されていれば、すべての MathML 要素は接頭辞とともに用いられなければなりません。

<!ENTITY % MATHML.prefixed "INCLUDE" >

たとえば、<m:mrow><m:apply> のようになります。 接頭辞のデフォルトは m: ですが、パラメータ実体MathML.prefix で他の接頭辞を宣言することもできます。たとえば、

<!ENTITY % MATHML.prefix   "math" >

と宣言すれば、MathML 名前空間用の接頭辞は math: になります。

[Namespaces] 勧告は、文書中の任意の位置で接頭辞を変更するメカニズムを提供していますが、この柔軟性はこの DTD では 提供されない ということに注意してください (そして、どんなDTDでも指定することは不可能でしょう。たぶん)。

A.4 MathML を DTD なしで用いる

もしも MathML の断片がDTDなしでパースされる場合、 言い換えれば、正しい XML 断片としてパースされる場合、 トークン要素の周囲の空白文字が正しく処理されないのは 処理アプリケーションの責任です。

DTD が DOCTYPE 宣言とともに指定されていない場合、実体参照 (たとえば MathML 文字を名前で参照する場合) は利用できませんので、注意してください。

A.5 SGML

必要に応じて、XMLパーサーではなく nsgmls のような SGML パーサーで MathML 文書を validate することもできます。 この場合、SGML パーサーを XML レベルに抑制させる SGML 宣言を用いる必要があります。note on SGML and XML をご覧下さい。

古い SGML システムでは、plane 1 文字 (16進FFFF以上の Unicode 文字) を参照するファイルを処理することができない場合があります。

A.6 MathML の DTD

文字の実体宣言は DTD の最後で参照しています。 これらは、それぞれの実体セットに対して 第6章「文字、実体とフォント」 中の文字テーブルにリンクしています。

MathML 文字名のセットの一覧は、 名前順 もしくは Unicode 値順 でも用意されています。

XML 名前空間の接頭辞を可能にするため、 DTD では mrow のように直接的に要素名を参照していませんが、 代わりに常に名前を %mrow.qname; のようにパラメータ実体で参照しています。 これらのパラメータ実体の定義は、ファイル mathml2-qname-1.mod にありますが、ここでは示してありません。 これは、それぞれの MathML 要素に対し、以下のような単なる宣言をしたものです。

<!ENTITY % mrow.qname           "%MATHML.pfx;mrow" >

以下に、DTD の核となる部分を示します。 完全な DTD は、XHTML-Math DTD とともに、zip archive として用意してあります。
