I agree with Barry's editorial suggestions.

What does the "*)" in the table in Section 3.3 mean?

[ml] Thanks for spotting this. It's actually a leftover from a removed remark (editor's note) that we had in past revisions. We'll remove the tag from the table in revision 14.   


>From Section 10:

   [...]  if the Diameter client or server is
   compromised, an attacker could launch DoS attacks by terminating a
   large number of sessions with a limited set of commands using the
   session group management concept.

Is it worth mentioning that an attacker could also mess with the set of sessions associated with a group, possibly causing disruptions other than bulk session terminations?

[ml] yes, it's a valid scenario during an attack, too. We propose the following extension to the existing text to cover your proposal:

“..if the Diameter client or server is compromised, an attacker could launch DoS attacks by terminating or applying change operations 
to a large number of sessions with a limited set of commands using the session group management concept.”
