Hi Paul,

Already done.  Please see -12.

Thanks, I had a look. Why did the MUST get changed to a SHOULD? It is okay to state a MUST as well as an action when that MUST is violated ?

Or was there another reason to change it ?

Paul



Thanks,
Tony

These changes look fine to me. Please cut another draft and I will update my ballot to No Objection.

My proposal is unnecessarily draconian and disruptive. A better approach would be:

           Multiple proxy system identifiers in a single
           area is a misconfiguration and each unique occurrence
           SHOULD be logged. Systems should use the proxy system
           identifier advertised by the Area Leader.

I will maintain an increased level of caffeination. My apologies for the confusion.

Regards,
Tony
