As noted in an earlier response, it is WOXOF. That means nothing is moving. With vis and ceiling at zero/zero, you can not even taxi if you are part 121 or 135. Part 91 you can try it but it isn't smart.
Many airports have low visibility taxi charts and routes so you can grope you way either too or from the runway but when it gets to less than 600 or 330 RVR, it takes a long time to feel your way to the runway or the gate. And more than a few times before the airports got good ground radar, airplanes would be surprised to find themselves nose to nose with another airplane. NO FUN.
I've done a number of CatIIIB approaches and the approach and autoland was simpler and quicker than the taxi to the gate.
