Hi Tom,

Thanks for checking on PCEP-Yang.

It was part of the chairs slides #15
[https://datatracker.ietf.org/meeting/109/materials/slides-109-pce-1-introduction-01].
In the PCE WG, we usually capture only the discussion points in our
minutes.

I am aware of that discussion. IMHO at this stage, we can look again
at these sections and do a change only if it increases the
readability.

We did an early yang doctor review some time back, the authors are
suggesting another one soon. We can point them to your email as well
and see what they suggest.

No, PCE is not a routing protocol and thus does not follow the same convention.

Thanks!
