  # We can directly ask if xml object responds to the cache_me or
  # do_not_cache_me methods because xml is derived from BasicObject
  # (and repond_to? is not defined in BasicObject).
  #
  # Instead we are going to stub out method_missing so that it throws
  # an error, and then make sure that error is either thrown or not
  # thrown as appropriate.
