Well, I think there should be something obscure in the doc. if it made
you think that public methods call the corresponding private ones. It is
definitely not the case (at least by default, nothing prevents you from
doing this).

  Private accessors (as searched by KeyValueCoding.storedValueForKey)
  are the only one used by the framework. That's why they can be used,
  in particular, to define transformation from sql types to custom
  types.

Without more info. I cannot really tell why this bothers you so much :)
