+ * @bug 4507256
+ * @run main SetAttributeNode
+ * @summary Tests the functionality of IIOMetadataNode.setAttributeNode().
+ * Four separate tests are involved:
+ *   1) Tests whether a DOMException.INUSE_ATTRIBUTE_ERR is thrown if newAttr
+ *      is already an attribute of another Element object.
+ *   2) Tests whether setAttributeNode() returns the old attribute if it is
+ *      replaced.
+ *   3) Tests whether setAttributeNode() returns null if the new attribute is
+ *      not replacing an existing attribute.
+ *   4) Tests whether the new attribute successfully replaces an existing one.
