title: Displaying Mathml equations
body: <p>My browser, Firefox 3.6, seems to display the Mathml equations in the W3C test suite just fine. But if I copy the code into my webpage, like from <a href="http://www.w3.org/Math/testsuite/build/main/General/Math/mathAdisplay2-full.xhtml" rel="nofollow noreferrer">here</a>, all Firefox produces is something like <code>x y x y </code> instead of how it correctly rendered the W3C page. What am I missing here&gt;</p>
  <p><strong>EDIT</strong>: I just tried it in Chrome and Chrome failed the test itself by rendering it as <code>x y x y</code>. Needless to say, it rendered the math in my own webpage the same.</p>
  <p><strong>EDIT 2</strong>: I tried it on a new html document. Doesn't work:</p>
  <pre class="lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt;
  &lt;html lang=&quot;en&quot;&gt;
    &lt;head&gt;
      &lt;title&gt;&lt;/title&gt;
    &lt;/head&gt;
    &lt;body&gt;
  &lt;math display=&quot;inline&quot; xmlns=&quot;http://www.w3.org/1998/Math/MathML&quot; mode=&quot;display&quot;&gt;
    &lt;mfrac&gt;
      &lt;mi&gt;x&lt;/mi&gt;
      &lt;mi&gt;y&lt;/mi&gt;
    &lt;/mfrac&gt;
      &lt;/math&gt;
      &lt;math display=&quot;block&quot; xmlns=&quot;http://www.w3.org/1998/Math/MathML&quot; mode=&quot;inline&quot;&gt;
    &lt;mfrac&gt;
      &lt;mi&gt;x&lt;/mi&gt;
      &lt;mi&gt;y&lt;/mi&gt;
        &lt;/mfrac&gt;
      &lt;/math&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  <p>I swear the W3C equations render just fine though...</p>
