I don't believe you can change the class of a DOM node quite like  
that.  I know you can make the DOM node an attribute of another  
class.  And I believe you can also use something like node.prototype  
to add your own methods and attributes to the DOM node object  
definition, but that's beyond anything I've done in JavaScript so  
someone else will need to explain how prototypes work.

Peace,
