yes, I was talking about real world objects that are represented as
nodes in OSM

not such a good solution. 

For real-world-node-objects where the node is part of the tunnel/bridge 
way I think it can be expected that his node implicitly shares the tunnel
+layer values.

That leaves the problem with objects where the node is *not* part of the 
tunnel/bridge way such as a waste basket next to the way. 
Seems like in this case a relation is needed ?
