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.
