title: What does Firebug "XML cannot be the whole program" error message mean?
body: <p>I just got this error message in Firebug. A google search reveals nothing but other mystified people! Does anyone have any idea what it means?</p>
  
  <p>It's being indicated on the last line of this 3-line script:</p>
  
  <pre><code>&lt;script&gt;
      g_BuildServer = "/";
  &lt;/script&gt;
  </code></pre>
