Gyan>This is a confusing point and maybe something the authors can
clarify in the text. So this draft defines a new Adj-Sid that has an Algo
identifier specifically for Flex Algo and if that’s the case I agree it
does not update the SR-MPLS IGP extensions, but instead should update the
Flex Algo extensions.
