The two complement each other, in fact.  If the TIGER data says that
the houses on a block run from 2-100, but the actual situation is that
they run from 2-20, you can put 2-20 in the Karlsruhe schema and leave
the TIGER data as is.  Then if house 22 gets added on to the end of
the block, and someone asks the geocoder where it's located, the
geocoder can at least say "well, it's supposed to be on this block"
rather than "sorry, house doesn't exist".
