This is reason why Michael is in CC: :-)

There is no extN stuff anymore in mount.8.

Unfortunately, it's nothing unusual that mount.8 is ignored by FS
devels and not up to date... so the idea is keep FS docs near to 
the FS developers to improve things ;-) 

For example NFS developers have decided to maintain it in nfs-utils,
extN in e2fsprogs, tmpfs and procfs in Michaels' man-pages, etc.

Anyway, I have no problem to maintain UDF (or another) mount options 
in mount.8. It's your choice. Your patches for mount.8 are welcomed.
