Hi Acee,

There is one remaining question in RFC-to-be 9903 for Jeffrey Zhang. See here:
https://mailarchive.ietf.org/arch/msg/auth48archive/AF0rJKKqn5DzpmJ_lCS2ZgoC66E/

Once that question is addressed, we will move both documents in C542 forward in 
the publication process.

Thank you,
Alanna Paloma
