The spec says if "there is no word in the dictionary that can be used in the partial encoding starting at digit k+1" then a digit can be used. Some people interpreted that as "no word from the dictionary can be used in a solution". Others interpreted that as "no word from the dictionary can be used for a single word addition" :)
