If an application needs information about notations and unparsed entities, it can implement this interface and register an instance with
setDTDHandler().Note that this interface includes only those DTD events that the XML recommendation requires processors to report, i.e. notation and unparsed entity declarations using
notationDecl()andunparsedEntityDecl()分别。
