title: how to add the custom elements in the RTF field of a component in SDL Tridion 2011 Sp1
body: <p>I want to add custom elements in the source of a Rich Text field in SDL Tridion. Is there any chance to add them by changing the XSL filtering in the Schema?</p>
  
  <p>Example:</p>
  
  <p>I have a RTF field "text" in SDL Tridion. I want to add something like this:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;text&gt;
      &lt;customelement&gt;the text added through the custom element&lt;/customelement&gt;
  &lt;/text&gt;
  </code></pre>
  
  <p>Can somebody help me on this?</p>
  
  <p>Thanks.</p>
