I have carried out the SecDir review for the -02 version, and all my nit concerns are addressed in current -16 version. But about my one question, I have not seen any response or actions: "Issues for clarification: In Security Considerations, besides the DoS attacks brought by the malicious payloads, is there any other kinds of attack possibly? For example, virus or worm are hidden in the malicious payloads to attack the system for more damages? Does it make sense and what's the consideration?" This time, is there any clarification? Thanks!
