That's what udevinfo is for. You may look at the output of:
  udevinfo -a -p <DEVPATH>

and
  udevinfo -s

to get an idea. I've added the -s option while I was working on
wait_for_sysfs. It's not generally useful and it may be nice to move
some of that functionality into the -a option to provide the user with
the full list of possible keys to paste into a rule.

Thanks,
Kay
