You are right.  That section needs to be updated.

Look in /dev/disk/by-id/.  You should see a cd or dvd device.  In my 
case, I have:

disk/by-id/ata-PLDS_DVD+_-RW_DH-16A6S -> ../../sr0

If I do udevadm test /sys/block/sr0, I see

LINK 'cdrom' /usr/libexec/udev/rules.d/60-cdrom_id.rules:18

does that not work for you?
