Map entities that you can see on the ground. i realise there are some, 
like boundaries, but we have verifiable proof they exist.
For old railway line map the entities that remain, such embankments, 
bridges etc, but not the actual track if it's been removed or there's a 
housing estate built over it.

To repeat myself: OSM is a database of *current* entities.
