title: Design-time DataContext in a DataTemplate?
body: <p>When I put a <code>DataTemplate</code> in a <code>&lt;Page.Resources&gt;</code> section, it inherits the <code>DataContext</code> of the <code>Page</code> when editing bindings inside the designer. However at run-time the <code>DataTemplate</code> is being used by an element inside the <code>Page</code> which has its own <code>DataContext</code>. I want the designer to show the inner <code>DataContext</code> while binding instead.</p>
  
  <p>Is there a tag like <code>d:DataContext</code> for <code>DataTemplates</code>? Setting <code>DataType</code> doesn't do anything.</p>
