Yes. You have to import them (unless already done) on "add" event; those
values are stored in udev database and added to environment *before* rules
are being processed on "remove" event. At least that is the theory :)
You also can explicitly assign any environment variable on "add" and it should
be available as well on "remove". This allows you to mark any specific device
if you like.
