Hi,
Thank you for updating the draft. Nice to see T.M.Tmap was renamed to
T.M.GTP4.D corresponding to End.M.GTP4.E. :)
Some feedback about the updated description.

"The B’" is IPv6 SA so I think this should correspond to S' in
End.M.GTP4.E rather than to SID.
So it might be more clear to depict the packet format (diagram) again
and mention B' has the following format with the IPv4 SA of the
receiving packet.
0 127

Abstract:
This document shows the applicability of SRv6 (Segment Routing IPv6)
to the user-plane of mobile networks. The network programming nature
of SRv6 accomplish mobile user-plane functions in a simple manner.
The statelessness of SRv6 and its ability to control both service
layer path and underlying transport can be beneficial to the mobile
user-plane, providing flexibility, end-to-end network slicing and SLA
control for various applications. This document describes the SRv6
mobile user plane behavior and defines the SID functions for that.
