That is certainly a coherent position. Literals are self-denoting 
character strings, but they can have properties. That makes perfect 
semantic sense and would simplify the model theory, if anything. 
However it means that numerals don't denote numbers, which will be 
widely thought to be a bummer, I suspect.
