FWIW, I found that I was able to do (typing from memory):

class Foo < REXML::Element
  def clone
    klone = self.class.superclass.method( :new ).unbind.bind(
self.class ).call( self )
    # my stuff here
    klone
  end
end

...but I think I'll probably end up re-writing my class to
wrap/delegate to Element, instead of directly inheriting from it. Pity,
from an rdoc standpoint.
