The term "private data" is intended to convey the
intent that the data is private to the application
layer and is opaque to middleware and the network.

The private data area is for the use of whatever client resides above the Infiniband CM only. There is no assumption about whether that client is middleware or an application.

By what mechanism does the listening application
delegate how much of the private data for use by
the CM for sub-dividing a listen? What does an application do if it wishes to retain full ownership
of the private data?

An application that interfaces directly with the Infiniband CM always retains full control of any private data. Applications that interface to middleware are restricted by the limitations of that middleware layer.
