Yes.

There are assumptions about the services
provided that need to be made explicit.
However, if there is visibility of transport
session establishment and termination, there
is no need for visibility of the lifetime
information from RADIUS, since the RADIUS semantics
of session lifetime require the transport to terminate
the session upon expiration of the lifetime anyway.
