How does your "/etc/udev/rules.d/70-persistent-cd.rules" look like?

I thought udev should manage this automatically without needing to make 
static mount points in "/etc/fstab" in the same way it does when you 
insert an USB flash drive and it gets mounted under "/media/MYUSB_TAG" 
unless you tell otherwise :-?
