  Both a {@link #startElement startElement} and an
  {@link #endElement endElement} event will be passed on down
  the filter chain.
  
  @param uri The element's Namespace URI, or the empty string
  if the element has no Namespace or if Namespace
  processing is not being performed.
  @param localName The element's local name (without prefix).  This
  parameter must be provided.
  @param qName The element's qualified name (with prefix), or
  the empty string if none is available.  This parameter
  is strictly advisory: the writer may or may not use
  the prefix attached.
  @param atts The element's attribute list.
  @exception org.xml.sax.SAXException If a filter
  further down the chain raises an exception.
