CoreData - how to write new kind of PersistentStore?

FROM : Todd Blanchard

It would appear from the docs that the protocol for PersistentStore
itself is undocumented and that there is no api on
NSPersistentStoreCoordinator for registering new kinds of
PersistentStores.

Is this simply a case of the docs lagging the code, or is CoreData
pointlessly limited in this way?  Having the ability to add new
PersistentStores would be the key to allowing the use of CoreData with
legacy file formats.

Not having this ability is exactly the sort of short sighted limitation
I expected from an api developed in a vacuum.

Please, surprise me.
