title: OpenXML converting .docx to .doc
body: <p>I've successfully implemented OpenXML that takes the bookmarks within a document and replaces them. Unfortunately it only works with .docx and from what I understand .doc is not compatible with the OpenXML format.</p>
  
  <p>So, what I'm wondering is if I can take that <code>WordprocessingDocument</code> and convert it to a .doc when users try and download it. Is that possible? If so anyone know how to do that?</p>
