  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
