+<p>Essa é uma lista alfabética dos elementos de <strong>apresentação</strong> de MathML.</p>
+
+<p>O termo <strong>marcação de apresentação</strong> é usado para descrever a estrutura da notação matemática, enquanto que <strong>marcação de conteúdo</strong> fornece um significado matemático básico e não é feito para ser renderizado pelo parser de MathML (ver {{ bug(276028)}}). Se você desejar aprender mais sobre marcação de conteúdo considere o <a href="http://www.w3.org/TR/MathML3/chapter4.html">Capítulo 4</a> na <a href="http://www.w3.org/TR/MathML3/">especificação do MathML 3</a>.</p>

+<p>The top-level element in MathML is <code>&lt;math&gt;</code>. Every valid MathML instance must be wrapped in <code>&lt;math&gt;</code> tags.

+<p><strong>Notes</strong>: XHTML documents with MathML must be served as <code>application/xhtml+xml</code>. You can achieve that easily by adding the <code>.xhtml</code> extension to your local files. For Apache servers you can <a class="external" href="http://httpd.apache.org/docs/2.2/mod/mod_mime.html#addtype" title="http://httpd.apache.org/docs/2.2/mod/mod_mime.html#addtype">configure your <code>.htaccess</code> file</a> to map extensions to the correct Mime type. Since you notate your MathML in an XML document, also be sure you write a well-formed XML document.</p>
