A couple of minor issues and a couple of *extremely* nitty nits, but overall
looks ready to go.

Major issues:


Minor issues:

It is not clear to me why this is being sent for Informational instead of
Proposed Standard. The shepherd's writeup does not justify it, and in fact the
writeup refers to the document as a "specification", which is exactly what it
appears to be. It defines the use of SFLs, describes how they are processed by
the endpoints, describes how they are aggregated, etc. While the document may
not be standalone, I don't see how it's really an Informational document. I
suggest restarting the Last Call for Proposed, and if for some reason it needs
to be Informational, it can always be downgraded after Last Call.

The Security Considerations section says, "The issue noted in Section 6 is a
security consideration." I'm not sure I understand why that is.

Nits/editorial comments:

Section 1: "(see Section 3)" seems unnecessary.

Section 3: I thought the "Consider..." construction made those paragraphs
unnecessarily wordy and a bit harder to follow.
