COMMENT:
----------------------------------------------------------------------

Without having looked before I was thinking this was Standard Track, I'm
surprised it is not.

You say:
   1.  Push zero or more labels that are interpreted by the destination
       MPLS node on to the packet,
and then say:
   The receiving MPLS node then pops the SFF Label (and any labels
   beneath it)
So it looks like that any label which might have been pushed before the SFF
label is/are simply ignored at the other end. I'm not asking for the behaviour
to be specified and I understand that strictly speaking the text is not
forbidding something to happen based on these labels but still it might be
useful to explicitly say that these labels may be processed.
