 * @test

 * @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.
