    45  * The <code>Element</code> interface represents an element in an HTML or XML
       
    46  * document. Elements may have attributes associated with them; since the
       
    47  * <code>Element</code> interface inherits from <code>Node</code>, the
       
    48  * generic <code>Node</code> interface attribute <code>attributes</code> may
       
    49  * be used to retrieve the set of all attributes for an element. There are
       
    50  * methods on the <code>Element</code> interface to retrieve either an
       
    51  * <code>Attr</code> object by name or an attribute value by name. In XML,
       
    52  * where an attribute value may contain entity references, an
       
    53  * <code>Attr</code> object should be retrieved to examine the possibly
       
    54  * fairly complex sub-tree representing the attribute value. On the other
       
    55  * hand, in HTML, where all attributes have simple string values, methods to
       
    56  * directly access an attribute value can safely be used as a convenience.
       
    57  * <p ><b>Note:</b> In DOM Level 2, the method <code>normalize</code> is
       
    58  * inherited from the <code>Node</code> interface where it was moved.
