`MxValue`, `MxArray`, and `MxStatusProxy`.
The public command model includes bulk subscription command kinds for
`AddItemBulk`, `AdviseItemBulk`, `RemoveItemBulk`, `UnAdviseItemBulk`,
`SubscribeBulk`, and `UnsubscribeBulk`. These commands are normal unary

`BulkSubscribeReply` containing per-item `SubscribeResult` records with
`ServerHandle`, `TagAddress`, `ItemHandle`, `WasSuccessful`, and
`ErrorMessage`.

calls sequentially on the session STA and preserves input order in the result
list.
