title: xml tag with a dot in haml
body: <p>I have a tag that contains a dot (.) that I want haml to preserve:</p>
  
  <p>Haml:</p>
  
  <pre><code>%text
   %text.resource
    ...
  </code></pre>
  
  <p>I would like Haml to expand to:</p>
  
  <pre><code>&lt;text&gt;
     &lt;text.resource&gt;...
     &lt;/text.resource&gt;
  &lt;text&gt;
  </code></pre>
  
  <p>but it keeps doing:</p>
  
  <pre><code>&lt;text&gt;
     &lt;text class="resource"&gt;...
     &lt;text&gt;
  &lt;text&gt;
  </code></pre>
  
  <p>Is there any easy way to "escape" "class" expansion in Haml?</p>
