title: Use XML code in string.format
body: <p>I was wondering if it is possible to use string.Format to make certain text's say bold, and other italic? Something like </p>
  
  <pre><code>string.Format( "&lt;Bold&gt;{0}&lt;/Bold&gt;", some text in bold );
  </code></pre>
  
  <p>is this possible, or should I add a Bold every time I want to add something in Bold?</p>
