Hey Michael,

Be careful when validating/editing.

I assume you extracted artwork node from wall. Why did you do this?
Artwork node on wall is usually okay, even if of type sculpture/statue/installation/... (which this is not)

https://www.openstreetmap.org/node/10801169424
survey point is even explicitly usually part of wall or similar.

Do not blindly trust the validator application(!)
https://wiki.openstreetmap.org/wiki/Good_practice#Don't_remove_objects_that_you_don't_need_or_like

If object is too close to something else then it might be better viewed with a different editor application / check if editor application has a way to do so, i.e. in iD press W for wireframe mode, or in iD/JOSM use data filters, or in 3D editor select level/layer.
If it shares a node with entrance / highway it is not always wrong, some mappers may just approach this differently.
Accepting fixes from validator blindly may also result in connecting it to different, unrelated objects.
You can always ask in changeset from contributor why they placed it so close / connected it to something else.

Regards,

Daniel
