module: fortios_system_vdom_exception
short_description: Global configuration objects that can be configured independently across different ha peers for all VDOMs or for the defined VDOM scope in
   Fortinet's FortiOS and FortiGate.
description:
    - This module is able to configure a FortiGate or FortiOS (FOS) device by allowing the
      user to set and modify system feature and vdom_exception category.
      Examples include all parameters and values need to be adjusted to datasources before usage.
      Tested with FOS v6.0.0
version_added: "2.0.0"

notes:
    - We highly recommend using your own value as the id instead of 0, while '0' is a special placeholder that allows the backend to assign the latest
       available number for the object, it does have limitations. Please find more details in Q&A.
    - Legacy fortiosapi has been deprecated, httpapi is the preferred way to run playbooks

    - The module supports check_mode.
