77*
78    The "setAttributeNode(newAttr)" method returns the
79   null value if no previously existing Attr node with the
80   same name was replaced.
81
82   Retrieve the last child of the third employee and add a
83   new attribute to it.  The new attribute node added is
84   "lang", which is not part of this Element.  The
85   method should return the null value.
86   This test uses the "createAttribute(name)"
87   method from the Document interface.
