title: MusicXML Division and Duration
body: <p>I have an MXL file from some test suite in which the first measure says Division is 8 (i.e. 8 units per quarter note).</p>
  
  <p>Measure 4 is in 3/4 time and has the following rest:</p>
  
  <pre><code>&lt;note&gt;
      &lt;rest measure="yes"/&gt;
      &lt;duration&gt;24&lt;/duration&gt;
      &lt;voice&gt;1&lt;/voice&gt;
  &lt;/note&gt;
  </code></pre>
  
  <p>I would expect to see <code>&lt;dot/&gt;</code> here. As 24 divided by 8 is 3, am I supposed to infer that this note should be dotted? Does this mean I'll have to write code for a special case where <code>&lt;dot/&gt;</code> is missing but the note is clearly supposed to be dotted?</p>
  
  <p>I'm confused by this representation. I wish they'd made the <code>type</code> attribute mandatory myself... If anyone could explain how dotted and tuplet durations are supposed to be represented, I'd appreciate it.</p>
