      Description



      Name: inR10064 Date: 10/26/2000



        When JAXP 1.1 method org.w3c.dom.Document.importNode(Node importedNode,
                                                             boolean deep)
      is used to import an attribute from another document to current document, it
      returns imported attribute with non-null owner element (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#i-Document) says:

      " importNode introduced in DOM Level 2
        ....
            ATTRIBUTE_NODE
              The ownerElement attribute is set to null and the specified flag is set
              to true on the generated Attr. The descendants of the source Attr are
              recursively imported and the resulting nodes reassembled to form the
              corresponding subtree. Note that the deep parameter has no effect on
              Attr nodes; they always carry their children with them when imported. "
              
      This bug presents in builds jaxp-1.1ea-b8, jaxp-1.1fcs-b9 and jaxp-1.1ea2-b10 and
      affects the new test in TCK JAXP 1.1
      api/org_w3c_dom/Document/ImportNodeTests.html#importNodeTest001.
