Sal: Thanks.  Closing the loop on one of your previous comments
that I have not yet responded to ... see [1].

To fix this, I suggest the following change:

OLD:
9.2 Backwards Compatibility
...
    A SIP server should therefore use 5xx responses towards upstream
    neighbors that do not support overload control. The server should
    reject the same amount of requests with 5xx responses that would be
    otherwise be rejected/redirected by the upstream neighbor if it would
    support overload control. If the load condition on the server does	
    not permit the creation of 5xx responses, the server should drop all
    requests from servers that do not support overload control.

NEW:
9.2 Backwards Compatibility
...
    A SIP server should therefore follow the behaviour outlined in
    Section 5.10.2 to handle clients that do not support overload
    control.

Thanks,
