      Description



      Name: inR10064 Date: 12/13/2000



        JAXP 1.1 method
              org.w3c.dom.NamedNodeMap.removeNamedItemNS(String namespaceURI,
                                                       String localName)
              
      does not replace the attribute which has a default value. Instead of this it removes
      the attribute from the map (See test.java below).

        Definition of the method in p. 1.2 "Fundamental Interfaces" of DOM Level 2 Core
      (http://www.w3.org/TR/DOM-Level-2-Core/core.html#ID-1780488922) reads:

      " removeNamedItemNS introduced in DOM Level 2
           Removes a node specified by local name and namespace URI. A removed attribute
           may be known to have a default value when this map contains the attributes
           attached to an element, as returned by the attributes attribute of the Node
           interface. If so, an attribute immediately appears containing the default value
           as well as the corresponding namespace URI, local name, and prefix when
           applicable. "

      This bug is found in builds jaxp-1.1ea-b07, jaxp-1.1ea-b08, jaxp-1.1ea-b09,
      jaxp-1.1ea2-b10, jaxp-1.1ea2-b11, jaxp-1.1ea2-b12, jaxp-1.1ea2-b13, jaxp-1.1ea2-b14
      and affects the new test in TCK JAXP 1.1
