title: Create a rounded SVG rectangle with multiple borders?
body: <p>In XAML there is the concept of a [Border] object that behaves much like an SVG rectangle except that a XAML [Border] can contain a child element.</p>
  
  <p>So I could create a [Border] with a black stroke and inside it have another border that had a white stroke and a fill of Green.</p>
  
  <p>This gives the the look of a single rectangle with both a black border &amp; then an inner white border.</p>
  
  <p>How can you create this in SVG?</p>
