      Name: viR10068 Date: 05/07/2002



      The api doc for the interface DeclHandler the method
      public void externalEntityDecl(String name, String publicId, String systemId)
                              throws SAXException
      says:
      "Only the effective (first) declaration for each entity will be reported."

      But the xerces in JAXP 1.2 build b18 reports both entity declaration.
      Note, the crimson in JDK 1.4.1 reports only one.

      See the log below for details:
