actually man udev specifies both:
ATTR{filename}
Match sysfs attribute values of the event device. Trailing
whitespace in the attribute values is ignored, if the specified match
value does not contain trailing whitespace itself.
ATTRS{filename}
Search the devpath upwards for a device with matching sysfs
attribute values. If multiple ATTRS matches are specified, all of them
must match on the same device. Trailing whitespace in the attribute
values is ignored, if the specified match value does not contain
trailing whitespace itself.
Not that this helps my understanding any more, i am lost for sure.
