The download acknowledgement is sent after the download has been fully applied and committed at the remote (a positive acknowledgement)
or after the download fails (a negative acknowledgement).
Set True to specify that the client should send a download acknowledgement to the MobiLink server. Set False to specify that
no download acknowledgement is sent. The default is False.
If the client sends a download acknowledgement, the MobiLink server database worker thread must wait for the client to apply
and commit the download. If the client does not sent a download acknowledgement, the MobiLink server is freed up sooner for
its next synchronization.
