title: WiX statement "CDATA[NOT Installed]" is not working
body: <p>I am trying to make the DemoDatabaseDlg dialog conditional, so if it is the FIRST time the user is installing the installer then "DemoDatabaseDlg" should be displayed. If it is NOT the first time installation then skip this dialog and jump to the next dialog.</p>
  
  <pre><code>  &lt;Publish Dialog="WelcomeDlg" Control="Next" Event="NewDialog" Value="DemoDatabaseDlg"&gt;1&lt;/Publish&gt;
  
    &lt;Publish Dialog="DemoDatabaseDlg" Control="Back" Event="NewDialog" Value="WelcomeDlg"&gt;
      &lt;![CDATA[NOT Installed]]&gt;
    &lt;/Publish&gt;
  
    &lt;Publish Dialog="DemoDatabaseDlg" Control="Next" Event="NewDialog" Value="PrepareDlg"&gt;1&lt;/Publish&gt;
    &lt;Publish Dialog="ExitDialog" Control="Finish" Event="EndDialog" Value="Return" Order="999"&gt;1&lt;/Publish&gt;
  </code></pre>
  
  <p>However, after the first installation, when I try to increase the version number and re-install again, I still CAN see the DemoDatabaseDlg dialog. How can I skip this dialog using CDATA conditions?</p>
