title: XML false vs (string) false
body: <p>How can I represent, true/false as the Boolean and "true"/"false" the strings in XML?</p>
  
  <p>Eg.</p>
  
  <pre><code>&lt;problem&gt;false&lt;/problem&gt;
  &lt;problem&gt;problem_name&lt;/problem&gt;
  </code></pre>
  
  <p>Or is there a better way to do this?</p>
