title: issue with DataTemplate on WP7
body: <p>I have a <code>DataTemplate</code> that is defined in App.xaml and is used in 2 places (<code>ItemControls</code>).</p>
  
  <p>It works perfectly for both except for color of the text.</p>
  
  <p>I assumed that if i define a brush as a <code>StaticResource</code> at those 2 places with different value it would work, as it will move up thru the visual tree trying to find the brush resource. But as <code>DataTemplate</code> is defined in <code>App.xaml</code> it looks for the brush only in App resources, not in the place where the <code>DataTemplate</code> is used.</p>
  
  <p>Can i somehow reuse the <code>DataTemplate</code> in 2 places with custom brushes (without any global brush in App.xaml) </p>
