title: ContentPresenter DataTemplate
body: <p>I have a <code>DataTemplate</code>:</p>
  
  <pre><code>&lt;DataTemplate x:Key="myTemplate"&gt;
      ...
  &lt;/DataTemplate&gt;
  </code></pre>
  
  <p>I want to use it as the <code>ContentTemplate</code> of a <code>ContentPresenter</code>:</p>
  
  <pre><code>&lt;ContentPresenter Content="{Binding X}"&gt;
      &lt;ContentPresenter.ContentTemplate &gt;
          &lt;!-- ????? what goes here ????--&gt;
      &lt;/ContentPresenter.ContentTemplate&gt;
  &lt;/ContentPresenter&gt;
  </code></pre>
  
  <p>How can I use the predefined <code>DataTemplate</code> in my <code>ContentPresenter</code>?</p>
