> We can do that. But is the intention that these function are public? We really only need them internally. It is possible that they could be used somewhere else but probably not likely. How about if we document them but mark them as @internal in Doxygen. Then if they are require by some other libs they can be made external at a later stage.

Yes they can be marked @internal with rte_ prefix.
