The callback is only on datasets because the callbacks are between fetch
operations on the server. When using TIB_DSQL there are no opportunities to
produce callbacks. It's actually a little misrepresentative to call them
callbacks because it isn't the server actually facilitating client
interruption via callbacks. It is purely a callback from the IBO core
fetching routines only.
