Hi Kalyani, Thanks for the feedback.
Looking at the LS, I see the deadline as July 20th. Is that a mistake? Unfortunately, we were going by the date listed in the LS. https://urldefense.proofpoint.com/v2/url?u=https-3A__datatracker.ietf.org_l iaison_1572_&d=DwIFAg&c=udBTRvFvXC5Dhqg7UHpJlPps3mZ3LRxpb6__0PomBTQ&r=IdiSO Dh8aDRjdCeGgd9MznLHMYKgKcs_YSwXBDiaofh47oilzaXYRYETcBynUdpT&m=DpwNaCrfXd9EI fo9xBxDQO1_hSmvZiI6uiV6fYe3rYU&s=4575vR5rygFrP_tvoH2z0iDv1njzued0M1dNS0wbTT s&e= Deadline: 2018-07-20 Action Needed I do not know if we will be able to close this by 8th July.
