title: Escaping Curly Braces in AS3's XML variable
body: <p>I am trying to create a XML variable but I need to include a <code>{</code> and <code>}</code> in it.  </p>
  
  <pre><code>public class MyClass {
  
      private var simple:XML = 
          &lt;config&gt;
              &lt;url&gt;{PROTOCOL}://{SERVER}/{FOLDER}/&lt;/url&gt;
          &lt;/config&gt;
  
  
      ...
  
  }
  </code></pre>
  
  <p>Flex is trying to find a variable named <code>PROTOCOL</code>, <code>SERVER</code> and <code>FOLDER</code>.  I need to prevent this by escaping the curly brackets.  </p>
  
  <p><strong>Question:</strong> How can I escape curly braces?</p>
