27 * @run main SetAttributeNode
28 * @summary Tests the functionality of IIOMetadataNode.setAttributeNode().
29 * Four separate tests are involved:
30 *   1) Tests whether a DOMException.INUSE_ATTRIBUTE_ERR is thrown if newAttr
31 *      is already an attribute of another Element object.
32 *   2) Tests whether setAttributeNode() returns the old attribute if it is
33 *      replaced.
34 *   3) Tests whether setAttributeNode() returns null if the new attribute is
35 *      not replacing an existing attribute.
36 *   4) Tests whether the new attribute successfully replaces an existing one.
