  <p><strong>NOTE:</entity> entity references in attribute
  values -- and the start and end of the document entity --
  are never reported.</p>
  
  <p>The start and end of the external DTD subset are reported
  using the pseudo-name "[dtd]".  All other events must be
  properly nested within start/end entity events.</p>
  
  <p>Note that skipped entities will be reported through the
  {@link org.xml.sax.ContentHandler#skippedEntity skippedEntity}
  event, which is part of the ContentHandler interface.</p>
  
  @param name The name of the entity.  If it is a parameter
  entity, the name will begin with '%'.
  @throws SAXException The application may raise an exception.
