title: How to use HTML inside ZF2 FlashMessenger
body: <p>I want to use an <code>&lt;a&gt;</code> inside a flashMessenger message.</p>
  
  <p>For example:
  In my website I have some blog posts, and when I delete one of them, I want to show a message like:
  "<code>Success! &lt;a&gt;Undo&lt;/a&gt;</code>"</p>
  
  <p>My code:</p>
  
  <pre><code>  $restore = $this-&gt;url()-&gt;fromRoute('news/restore', array('id' =&gt; $id));
    $this-&gt;flashMessenger()-&gt;addSuccessMessage("Success. &lt;a href='$restore'&gt;Undo&lt;/a&gt;");
    return $this-&gt;redirect()-&gt;toRoute('news');
  </code></pre>
  
  <p>But It doesn't work when I put that <code>&lt;a&gt;</code> inside the message.
  How can I do that?</p>
