### Orchestration Status for Dual Matching

For containers that are part of the dual matching, the new “dual_status” section will be sent as part of the “appointment_info” attribute, indicating the “matched”, “pending match” or “no match” state.

Once a match has been established, the “units” entry for the dual container will indicate a “dual_type” of either "AD" (Actual Dual) or "VD" (Virtual Dual).
