Certainly. I don't think we've been proceeding recklessly so far, have we?

It's not the direction I had been thinking in, but Tony Li got there first and 
suggested [1] a change that I think would get the job done. It has the merit of 
being a minimal update to the published text. The change would be,

OLD:
2.1.1.1.  V-Flag and L-Flag

NEW:
2.1.1.1.  V-Flag, L-Flag, and the SID/Index/Label Field

Absent further discussion, I'll plan to open an editorial erratum with that 
proposal; in light of the alleged waves, I will get it done by end of week, 
possibly today. Since I'll be the one opening it, and since it's not completely 
uncontentious, I'll ask one of the other ADs to handle verifying or rejecting 
it.

—John
