Re: I-D Action: draft-ietf-idr-segment-routing-te-policy-08.txt

Hi Ketan,
 Thank you for the updated version. I'm still reviewing it, but spotted
something I wanted to quickly clarify.

ver-7 of section "4.2.1. Acceptance of an SR Policy NLRI" had text
mandating RFC7606 TAW if acceptance criteria fail. In ver-8 this has been
removed, and I can't quite tell what text in section "5 Error Handling"
covers this? I'm assuming we still want to do TAW if acceptance criteria
fail.
Please clarify.

Thanks,
Nandan
