All declarations with the same name are reported

Name: dkR10031 Date: 07/31/2002


  
All attribute and entity declarations with the same name are reported
during the parsing an xml document (see DeclHandlerTest.java below). But
descriptions of the corresponding event methods read:

    org.xml.sax.ext.DeclHandler.attributeDecl()
      "Only the effective (first) declaration for an attribute will be reported."

    org.xml.sax.ext.DeclHandler.internalEntityDecl()
    org.xml.sax.ext.DeclHandler.externalEntityDecl()
      "Only the effective (first) declaration for each entity will be reported."

This issue is found in jaxp-1.2.0-fcs-b21 with help of the new JCK 1.4a
tests:
api/org_xml/sax/ext/DeclHandler/index.html#Decl[Decl113],
api/org_xml/sax/ext/DeclHandler/index.html#EntityDecl[EntityDecl006],
api/org_xml/sax/ext/DeclHandler/index.html#EntityDecl[EntityDecl104].
