title: Using XAML vector graphics in WPF application
body: <p>I have a vector image that I've defined in XAML. What is the proper way to use this resource in a WPF application?</p>
  
  <p>I want to have the vector image in its own XAML file, and then add the image to other UserControls in my application. What should be the top-level element in my XAML vector image? How do I refer to that image in other UserControls?</p>
