title: How to embed xml in xml
body: <p>I need to embed an entire well-formed xml document within another xml document.  However, I would rather avoid CDATA (personal distaste) and also I would like to avoid the parser that will receive the whole document from wasting time parsing the embedded xml.  The embedded xml could be quite significant, and I would like the code that will receive the whole file to treat the embedded xml as arbitrary data.</p>
  
  <p>The idea that immediately came to mind is to encode the embedded xml in base64, or to zip it.  Does this sound ok?</p>
  
  <p>I'm coding in C# by the way.</p>
