It still looks like a list of actions to take to me, so if it is
supposed to be unordered I'd prefer to swap SASL and TLS so it fits
[SASL] if one does take it to be ordered.  That seems more important
than listing it in the order which looks more graceful.


BTW, just to have stated it publicly: I didn't quite understand your
previous objection to "SASL and TLS layers" without comma, and as
discussed privately I disagree with part of your previous message
anyway, but hopefully that's irrelevant now.
