`building:part=parking` -> `parking=multi-story` within `building=yes`
Have I tagged this [building](https://www.openstreetmap.org/way/894616437#map=19/-33.92834/18.44303) correctly?
outline -> with the `address, name and building:levels=8`
`building:part=retail` -> `level=1` `building:levels=1`
`building:part=:parking` -> `parking=multi-story, min_level:1, level=3` building:levels=3`
`building:part=residential` -> `min_level:3, level=8` building:levels=8`
Then the parking garage entrance -> `parking=multi-story`.
The entrance is obviously at ground level but parking is on the 1st and 2nd level.

Would the same rational apply if the parking is underground?
