body: <p>Which XML structure allows me faster adding,deleting,updating of a node?</p>
  
  <p>My assumption is the first one as the xml hierarchy is not that deep.</p>
  
  <p>What do you think ? </p>
  
  <pre><code>&lt;Departments&gt;
     &lt;Department Id="a Guid" IsVisible="True" /&gt;
  &lt;/Departments&gt;
  </code></pre>
  
  <p><strong>OR</strong></p>
  
  <pre><code>&lt;Departments&gt;
     &lt;Department&gt;
        &lt;Id&gt;a Guid&lt;/Id&gt;
        &lt;IsVisible&gt;True&lt;/IsVisible&gt;
     &lt;/Department&gt; 
  &lt;/Departments&gt;
