详细描述

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() and unparsedEntityDecl() 分别。
