Lou,

I prefer option (b). The reason is that the IP flows sourced from an IP
node are already covered in section 6 of draft-ietf-detnet-dp-sol-ip-00,
while section 7 of that draft is the proper place for the draft-malis text,
and already contains a placeholder for it. It will indeed reference the
MPLS draft for the definition of the S-Label, Control Word, etc.

Cheers,
Andy
