title: Is it possible to define an XSD that doesn't care about additional elements?
body: <p>I have an XSD that defines and element which has been decrecated for some time, I now wish to remove this element and remove it from the class definition (I'm using the .net XmlSerializer with an XmlReaderSettings set to fire validation events).</p>
  
  <p>I'd like some of our clients who can't / won't remove the deprecated element from their xml to still be able to use my service, but I don't want to retain the additional Properties in my code or the xsd file (that way new client won't get the property and call me asking what it means)</p>
  
  <p>Is this possible?</p>
