*hrm* it would _really_ use better documentation! I already tried what
you've described without any success using:

udev_device_get_property_value() <- no description at all!

however it does work with:

udev_device_get_sysattr_value ()

sysattr ? property ? tags ? this is all confusing and again, reference
manual is not documentation. But it works, so thanks!
