There is definitely a difference, the question is, whether it is 
possible for an attribute to be "unknown" if it has a mapper.  On the 
one hand I kind of like including it here, because then we can treat all 
attributes equally (they all have a mapper) rather than "unknown" as a 
special case, but then we have to do the additional (small) change of 
inflating a do-nothing mapper for every unknown attribute we come 
across.  Which i think is OK.
