NIST The "setAttributeNode(newAttr)" method returns the null value if no previously existing Attr node with the same name was replaced. Retrieve the last child of the third employee and add a new attribute to it. The new attribute node added is "district", which is not part of this Element. The method should return the null value. This test uses the "createAttribute(name)" method from the Document interface. Mary Brady 2001-08-17
