wrong validation result "building inside building"

[dieterdreist]

When you have 2 multipolygons at the same spot (same members), one tagged as shop=* the other tagged building=* you get a warning "building inside building", but a shop is not a building. For example way 229760442

I flagged this as major because it discourages mappers to distinguish between the building and the user of the building by wrongly interpreting a shop tag (and maybe other tags) as buildings.

I did attach a sample file.

• the primary problem is that a simply multipolygon with two outer ways already produces a warning.
• considering the shop problem the two relations produce a different warning, as they have the same members but not building inside building.
