At first: you should probably CC Pierre for these PA related parts as well.

I'd probably remove that whole paragraph since we reference RFC 7084
anyway and this seems duplicate and was taken from there originally.

Maybe 1 or 2 extra modifications are necessary, see section 11.
I've queued something for the next revision.


Cheers,

Steven
