Question: What happens to an earlier version of a metadata envelope item when a newer version (higher version number) is received by the User Equipment (UE)?
Option 1: The earlier version remains active until manually expired by the service provider.
Option 2: The earlier version automatically expires, and the UE uses the new metadata fragment description if the content type is recognized and valid.
Option 3: The UE rejects the newer version if the increment is greater than one from the previously received version.
Option 4: The earlier version is archived for future reference, alongside the newly received version.
Explanation: When a newer version of a metadata envelope item is received, it automatically expires the earlier version. However, the UE will only use the new metadata fragment description if the content type is recognized and valid; otherwise, it may maintain the expired version temporarily until the newer one is correctly received.
