NIST The "setPrefix(prefix)" method raises a NAMESPACE_ERR DOMException if the specified prefix is xml and the namespaceURI is different from http://www.w3.org/XML/1998/namespace. Attempt to insert "xml" as the new namespace prefix on the first employee node. An exception should be raised since the namespaceURI of this node is not http://www.w3.org/XML/1998/namespace.
