--
-- This operation retrieves the following attributes from the 'lock-policy'
-- subresource set on the specified vault:
--
-- -   The vault lock policy set on the vault.
--
-- -   The state of the vault lock, which is either 'InProgess' or
--     'Locked'.
--
-- -   When the lock ID expires. The lock ID is used to complete the vault
--     locking process.
--
-- -   When the vault lock was initiated and put into the 'InProgress'
--     state.
--
-- A vault lock is put into the 'InProgress' state by calling
-- InitiateVaultLock. A vault lock is put into the 'Locked' state by
-- calling CompleteVaultLock. You can abort the vault locking process by
-- calling AbortVaultLock. For more information about the vault locking
-- process,
-- <http://docs.aws.amazon.com/amazonglacier/latest/dev/vault-lock.html Amazon Glacier Vault Lock>.
--
-- If there is no vault lock policy set on the vault, the operation returns
-- a '404 Not found' error. For more information about vault lock policies,
-- <http://docs.aws.amazon.com/amazonglacier/latest/dev/vault-lock-policy.html Amazon Glacier Access Control with Vault Lock Policies>.
