title: How can I utilize XAML objects specified in a resource dictionary in other XAML source?
body: <p>If i have a resource dictionary that contains something like </p>
  
  <pre><code>&lt;RibbonTab x:Key="HomeRibbonComponent" Header="test"&gt;
  
  &lt;/RibbonTab&gt;
  </code></pre>
  
  <p>how can I have my Ribbon control add this as a child? (in code it seems easy, in XAML not so much...)</p>
