title: What is the significance of POX ("plain old XML")?
body: <p>I've seen some references recently to POX or "plain old XML".  Is there a movement to simplify XML use?</p>
  
  <p>Wikipedia <a href="http://en.wikipedia.org/wiki/Plain_Old_XML" rel="nofollow noreferrer">says</a>:</p>
  
  <blockquote>
    <p>People typically use the term [POX] as
    a contrast with complicated,
    multilayered XML specifications like
    those for web services or RDF.</p>
  </blockquote>
  
  <p>Personally I find some of the usage of XML schemas and DTDs overly complex so I would welcome simplifying XML usage.  But maybe that's just me.</p>
