Using DDX to flatten a file

I have created the DXX below.However, when I use this module, it cuts a milti page form to a single page document. Can anyone explain why?

I also lose the logo from the file.

<?xml version="1.0" encoding="UTF-8"?>
<DDX xmlns="http://ns.adobe.com/DDX/1.0/">
  <PDF result="out.pdf">
    <PDF source="inDoc"/>
<NoForms/>
  </PDF>
</DDX>
