Rationale/Explanation of issue: All the commands defined in the draft
have a mandatory Auth-Application-Id AVP.  That makes it difficult to
use the command in a vendor application, since a vendor application
should use the command with a Vendor-Application-Id AVP and in RFC 
3588 it is stated that only one of these AVPs may be present.

Requested change: Change the message formats so that Auth-Application-ID
is optional.
