This is indeed a common trap, so some time ago I tried to point this out more clearly in the manpage: $attr{file}, %s{file} The value of a sysfs attribute found at the device, where all keys of the rule have matched. If the matching device does not have such an attribute, and a previous KERNELS, SUBSYSTEMS, DRIVERS, or ATTRS test selected a parent device, use the attribute from that parent device. This tries to point out that this won't match attributes from any parent device. Do you think this paragraph is unclear? If so, do you have a suggestion how to improve it? Or did you not see it in the first place?
