title: How to use HTML tags in interpolation syntax
body: <p>How can I use in interpolations HTML tags in HTML templates with Angular 2?</p>
  
  <p>For example:</p>
  
  <pre><code>&lt;h1&gt; {{title ? title : '&lt;i&gt;Title not set&lt;/i&gt;'}} &lt;/h1&gt;
  </code></pre>
  
  <p>If the <code>title</code> is undefined then there should be a <code>Title not set</code> in <code>i</code>-Tags.</p>
  
  <p>If I use the syntax above Angular will display exactly the expression (means with the {{, ?, :, }}) and does not evaluate it.</p>
