May be you intended to leverage the MEXT TS option, but it currently defines it as a new option (TSM). "4.3. Traffic Selector mobility option (TS) The Traffic Selector is a new mobility option that carries the parameters used to match packets for a specific flow mobility binding. The LMA MUST include 1 or more traffic selector mobility options in an FMI message."
