You shouldn't need it at all, just use the links in /dev/disk/ instead.
You can label your partition "external" and then mount
/dev/disk/by-label/external/ just fine.

Hi,
I have added the %n along with the name and fixed it. I am adding my
final rule, so that it will be useful to any other who is searching
for it ;-)
SUBSYSTEM="block", SUBSYSTEMS="scsi", ATTRS{model}="2500BEV
External", KERNEL="sd*", NAME="external%n"
Greg, thanks for the suggestion :-)
