Start with specification/automation/resource-manager/Microsoft.Automation/stable/2019-06-01/softwareUpdateConfiguration.json at the linked advancedSchedule definition, then compare it with the captured PUT and GET responses. Done means the API specification accurately represents the returned advancedSchedule data, with validation confirming the change.
