title: Differences in closing empty tags with XML
body: <p>In XML, is there a difference between this...</p>
  
  <pre><code>&lt;mytag&gt;&lt;/mytag&gt;
  </code></pre>
  
  <p>...and this?</p>
  
  <pre><code>&lt;mytag /&gt;
  </code></pre>
  
  <p>I understand that the latter is shorter and probably more idiomatic, but are they parsed differently?</p>
