title: Display <fb:loginbutton /> using xslt?
body: <p>I'm trying to display an facebook login-button in my xslt-rendered site. </p>
  
  <p>I'm putting</p>
  
  <pre><code>&lt;fb:loginbutton&gt;&lt;/fb:login-button&gt; 
  </code></pre>
  
  <p>in the xslt but my page just renders</p>
  
  <pre><code>&lt;login-button&gt;&lt;/login-button&gt; 
  </code></pre>
  
  <p>Why, and what can I do about it?</p>
