title: Can't load Flowdocuments with xml entites from textfile
body: <p>i doing a project with the wpf richtextbox control. I'm saving the textfile with the xamlwriter class.</p>
  
  <p>When i'm trying to load the file everything is working really well except if there are html entities in the file. Because the overloaded XamlReader class only excepts a stream or a XmlReader, the html entities ( in this case '&lt;' (<code>&amp;lt;</code>)  and  '>'  (<code>&amp;gt;</code>) are expanded and loaded into the xamlreader where an exception occurs because it thinks '&lt;' is an empty node. </p>
  
  <p>Are there any known workarounds? </p>
  
  <p>Thanks!</p>
