You are right. For each PDU session type you will have a different instance of
an End.M.GTP6.D SID. We can add a note in the next revision of the draft in
case this is not clear.

Subject: [DMM] Next Header in End.M.GTP6.D
In "6.2. End.M.GTP6.D", how would SR Gateway know if user packet inside GTP is
IPv4 or IPv6?
I think this info is required to set newly added SRH.NextHeader field in step
My understanding is that information would be provided by the control plane,
and if that's correct, should SR Gateway have 2 (or more) SIDs corresponding to
the type of user packet and also inform gNB to use different SIDs (dstAddr)
based on user packet type?
One could also have SID per TEID, but I'm not sure if that's a good design
choice considering the effort to reduce state in network nodes.
