title: How can I make a Button with multiple content values?
body: <p>My goal is to make a Button that has two Content values.  </p>
  
  <p>Imagine a Scrabble tile as a button: it has the large letter in the center and a small number in the lower right.  This is the effect I am going for.</p>
  
  <p>I made a button that has two ContentPresenter objects in it, and I have given each of the ContentPresenters a different style.  However, I have not found a way to give each of the presenters a separate value (ie, if I set the Content of the button to "X" then both ContentPresenters show "X", albeit in different styles).</p>
  
  <p>How can I achieve my objective?  I'm guessing my approach is completely wrong....</p>
