[OSM-talk] Postmortem analysys

I would suggest any (!) automatically dupe node analysis tool to respect 
every possible tag present at two nodes.
Even two nodes describing two doctors in one building with different 
opening hours are sometimes wanted to be at the same coordinates, there 
is nothing describing anything like level, elevation or layer; and 
nothing needed.
Collapsing these will produce wrong data as the opening hours of the one 
is connected to the other without intent.

At least the user pointed to some issue of that kind should be advised 
to be carefully - more carfully than at nodes without tags on the same 
location.

regards
Peter
