[Xufeng]: The current format is the result of long, back-and-forth
discussions among NETMOD and RGTWG working groups, and related ADs.
https://mailarchive.ietf.org/arch/msg/netmod/rqrXUqs8YMIfcrKZnSIoH4gA-8M
For now, we use this convention, until a new one is agreed on.

[Xufeng]: Fixed in revision -17.

[Xufeng]: For the example in Appendix C, we currently follow the format
from  https://tools.ietf.org/html/draft-ietf-netmod-rfc6087bis-20, which
does not use Copyright statement.
