// The 'access' tag '*_read' checks for any Sysconsole read permission and grants access if any read permission is allowed.

// Config values with the access tag 'cloud_restrictable' mean that are marked to be filtered when it's used in a cloud licensed
// environment with ExperimentalSettings.RestrictedSystemAdmin set to true.
//
// Example:
//  type HairSettings struct {
//      // Colour is writeable with either PermissionSysconsoleWriteReporting or PermissionSysconsoleWriteUserManagementGroups.
//      // It is readable by PermissionSysconsoleReadReporting and PermissionSysconsoleReadUserManagementGroups permissions.
//      // PermissionManageSystem grants read and write access.
//      Colour string `access:"reporting,user_management_groups"`
//
//      // Length is only readable and writable via PermissionManageSystem.
//      Length string
//
//      // Product is only writeable by PermissionManageSystem if ExperimentalSettings.RestrictSystemAdmin is false.
//      // PermissionManageSystem can always read the value.
