 The following arguments are supported:
 
 * `name` - (Required) The name of the SSM document to apply.
+* `sync_compliance` - (Optional) The mode for generating association compliance. You can specify `AUTO` or `MANUAL`.
 * `apply_only_at_cron_interval` - (Optional) By default, when you create a new or update associations, the system runs it immediately and then according to the schedule you specified. Enable this option if you do not want an association to run immediately after you create or update it. This parameter is not supported for rate expressions. Default: `false`.
 * `association_name` - (Optional) The descriptive name for the association.
 * `document_version` - (Optional) The document version you want to associate with the target(s). Can be a specific version or the default version.
