title: WSS 3.0: change parent type for a content type
body: <p>I have created a hierarchy of content types. The root of my hierarchy has the content type "Document" as a parent. There are about 20 other content types derived from my root.</p>
  
  <p>Now, I want to change the parent from "Document" to something else. Is it possible? Either in the web interface or in code? Can the definition of content types be dumped to a text file and then recreated? Or any other trick?</p>
