  <p>From <a href="http://en.wikipedia.org/wiki/Payload_%28computing%29" rel="noreferrer">wikipedia</a>: "*Payload in computing (sometimes referred to as the actual or body data) is the cargo of a data transmission. *"</p>
  
  <p>Does not make much sense here. Can anyone explain what payload / xml payload mean?
  Thanks. </p>
