Thanks for answering my questions.  Have you considered adding KAT
values for the key derivation steps?  This would be helpful to
implementors.  RFC5869 already has KAT values for HKDF-Extract and
HKDF-Expand.  But the TLS 1.3 spec has added HKDF-Expland-Label.
Additionally, It would be useful to show intermediate KAT values for
xSS, xES, mSS, and mES.
I suggest filing an issue or submitting a PR with a starting point set of 
changes and discussing it with ekr.


I've submitted https://github.com/tlswg/tls13-spec/issues/378. If you give me a few days, I'll update this issue with KAT values per revision 10. Since it sounds like there are changes forthcoming in this section of the draft, I'll hold off on the PR until later. Hopefully someone else will volunteer to verify my KAT values.
