: Diameter base protocol messages used by DCCA

In the process of attempting to construct a MIB for the credit control
application, I have been trying to figure out which messages from
Diameter base are used by DCCA, so that they can be counted
appropriately.  Some are obvious: STR/STA & RAR/RAA, for example.  One
has me rather puzzled, though: the AAR/AAA exchange is explicitly listed
in the first state machine in section 7 as being sent/received by the
CCA client, but the AVPs allowed in AAR/AAA are not listed in section 10
(though the APS for RAR/RAA ARE).  Does the CCA client actually
send/receive AAR/AAA (i.e., should the be counted in the DCCA MIB) or
not?
