NamedNodeMap.removeNamedItem removes attribute with default value

Name: inR10064 Date: 11/04/2000


  JAXP 1.1 method org.w3c.dom.NamedNodeMap.removeNamedItem(String name)
removes an attribute with default value from the map instead of replacing
it with a copy (See test.java below).

  Definition of the method in p. 1.2 "Fundamental Interfaces" of DOM Level 2 Core
(http://www.w3.org/TR/2000/PR-DOM-Level-2-Core-20000927/core.html#ID-1780488922)
says:

" removeNamedItem
     Removes a node specified by name. When this map contains the attributes
     attached to an element, if the removed attribute is known to have a
     default value, an attribute immediately appears containing the default value
     as well as the corresponding namespace URI, local name, and prefix
     when applicable. "

This bug presents in builds jaxp-1.1ea-b8, jaxp-1.1fcs-b9 and jaxp-1.1ea2-b10
and affects the test in TCK JAXP 1.1
