By way of additional minor follow-up:
* I think the addition of "." to the list of allowed characters should be a
  separate patch, rather than just added as part of this larger patch. If
  doing a separate commit to add boolean type, this could be a change in that
  set.
* There are a couple of API doxygen comments for the dictionary functions,
  rte_tel_add_dict_*, where the allowed characters in the name are called
  out. You probably should add "." to those comments too.
