permissions option in mount ntfs

I recently read this answer about mounting NTFS partitions in linux, so that I can change file and folder permissions (chmod). And they explain that I use the option "permissions". Example:

# fstabUUID=12102C02102CEB83 /mount_point  ntfs-3g  defaults,permissions 0 0# manualsudo mount /dev/sdax -t ntfs-3g -o permissions /mount_point

And works, but i checked man fstab and man mount and couldn't find the option "permissions". Search internet and in few places mention it, but without link to the source

Can someone tell me where this option comes from? (Provide an official link explaining this option). Thanks
