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. <br>
