 /**

  * <p>A specialized SAX2 XML parser that processes configuration objects.</p>
 21   
  *
 22   
  * <p>This class mimics to be a SAX compliant XML parser. It is able to iterate
 23   
  * over the keys in a configuration object and to generate corresponding SAX
 24   
  * events. By registering a <code>ContentHandler</code> at an instance
 25   
  * it is possible to perform XML processing on a configuration object.</p>
