Thank Eliot for pointing out these questions. I share a similar view with Qin, and I suggest to make the following changes in the next version:

1. draft-ietf-opsawg-tacacs will be changed as a normative reference according to RFC3967.

Several points: please take into account that RFC 8067 updates RFC 3967.  What this means is that you should probably have a brief chat with the chairs and Ignas on this point to see what he wants.  It may also be worth a little bit of discussion time.

Agreed on your points here.  I do think this should be a standards track document, and I think a downref would be acceptable in this case.  But this is worth addressing as an issue for your draft in your slot.



2. For the second point, I think your concern may be whether the TACACS + YANG model is flexible enough to accommodate the TACACS advanced features.

I think the augmentation is exactly what you want to do for this sort of thing.

This was also my thinking.  If/when a T+/TLS draft comes out and additional configuration is required, that could be an augmentation or even a bis to this model.  From a YANG versioning standpoint, we want models to evolve.

Joe
