No, not XML. It uses something MUCH better. It uses this:

$ cat rules.d/70-persistent-cd.rules 
# This file was automatically generated by the /lib64/udev/write_cd_rules
# program, probably run by the cd-aliases-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single line
# and set the $GENERATED variable.

# DVD+-RW_AD-7640A (pci-0000:00:1f.1-scsi-0:0:0:0)
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:1f.1-scsi-0:0:0:0", 
SYMLINK+="cdrom", ENV{GENERATED}="1"
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:1f.1-scsi-0:0:0:0", 
SYMLINK+="cdrw", ENV{GENERATED}="1"
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:1f.1-scsi-0:0:0:0", 
SYMLINK+="dvd", ENV{GENERATED}="1"
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:1f.1-scsi-0:0:0:0", 
SYMLINK+="dvdrw", ENV{GENERATED}="1"
# Mass_Storage (pci-0000:00:1d.0-usb-0:2:1.2-scsi-0:0:0:0)
SUBSYSTEM=="block", ENV{ID_CDROM}=="?*", 
ENV{ID_SERIAL}=="HUAWEI_Mass_Storage-0:0", SYMLINK+="cdrom1", 
ENV{GENERATED}="1"



See how fantastic this is? See how this conforms to The One True (Unix) Way?

See how it looks nothing like XML (invented by a Windows user, obviously), and 
actually looks a lot like perl with regexes?

On second thoughts, it looks nothing like perl. There aren't enough $, @ and % 
symbols in it. But the regex bit stands.
