building node part of building shape

[Famlam]

I spotted ​node 8793042989 where a (closed) building way contains a node with the same building tag, i.e. a node of the way equals the way itself.

Maybe it is interesting for JOSM to add the following rule to catch such cases?

way[building][building!=no]:closed > node[building][tag("building")==parent_tag("building")] {
  throwWarning: tr("{0} node part of {0} way", "{0.key}");
}

This is partly caught by the building inside building check. See source:trunk/resources/data/validator/geometry.mapcss@18667:186-190#L186​ .

Try adding building=shed to node 8793042988 and run the validator.

I think this might be a bug with ∈. I'd have to check the docs though.
