When a Scenery Object's Asset field is edited, the server attempts to extract the ATS field from the Asset name. The ATS name is then compared to this list. If there is a matching ATS entry in the list, the ATS asset is considered valid and will proceed with the edit.
If the ATS is not valid, the edit will be rejected.
This system is used because if the client is unable to download a missing ATS file, the client will fail with an error and need to be restarted. The server rejects the edit to safeguard the asset so that invalid "client-crashing" asset names are not saved and distributed by the server.
List file, each line contains a single name.
