25  * Neutral DOM level 1 Core Node implementation.
26  * All methods return <code>null</code> or <code>false</code>
27  * or throws an exception if they attempt to modify DOM tree
28  * or they are defined at higher DOM level. Clone method
29  * returns <code>this</code> as it probably safe for read-only DOM.
30  * <p>
31  * As a bonus it also implements some other DOM interfaces
32  * by throwing a DOMException.
