      Description



      Name: inR10064 Date: 11/04/2000


         When JAXP 1.1 method org.w3c.dom.Node.cloneNode(boolean deep) is used
      to clone an attribute of some element, it returns an attribute object
      which can't be added to another element by the method Element.setAttributeNode().
      DOMException is thrown with the INUSE_ATTRIBUTE_ERR error code (See test.java below).

        Definition of the method Element.setAttributeNode() 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-745549614)
      says:

      " Exceptions
          DOMException
              ......
              INUSE_ATTRIBUTE_ERR: Raised if newAttr is already an attribute of
              another Element object. The DOM user must explicitly clone Attr nodes
              to re-use them in other elements. "

      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
