i am running some address validation pipeline as others do aswell. In
Germany we have the case that most of the time the addr:city
on the addresses matches the name on the admin_level 8 boundary
(Sometimes admin_level 6).

So normally you have:


And all addresses carry a


Now there are some exceptions. One example i always paint red in the
validator is 33428 Marienfeld.

For Marienfeld there is an admin_level=8 which carries the
name=Harsewinkel which is correct for all "suburbs" or villages
belonging to Harsewinkel except Marienfeld.

Marienfeld itself carries a admin_level=9

So i'd like to have a place in OSM where i store this exceptions
information (There are plenty other places which have this

So i would propose to set an "addr:city=Marienfeld" on the admin_level=9
boundary. So the address validator knows that addresses contained within
this al9 should carry a different addr:city than they normally would
using the al8.

Other ideas?
