Right, except that it's written ATTR{}, not ATTR().

Not from the beginning, but NEWS documents this pretty well:

---------------- 8< ----------------
udev 098
========
Bugfixes.

Renaming of some key names (the old names still work):
BUS -> SUBSYSTEMS, ID -> KERNELS, SYSFS -> ATTRS, DRIVER -> DRIVERS.
[...]
---------------- 8< ----------------

098 was released in August 2006, so in software terms SUBSYSTEM and
ATTR have been around for ages.
