title: How to style heading labels in WPF/Silverlight/XAML?
body: <p>This seems simple enough, but I'm having difficulty finding an answer.</p>
  
  <p>I have a WPF window that requires use of headings and sub-headings for different areas.  Of course I could include the stlying inline for each element, but I'd really like to keep the styling separate.  What's the right way to semantically differentiate the various heading / sub-heading / "normal" label classes so that they can be properly styled in a separate XAML document?</p>
  
  <p>Thanks!</p>
