You can't really do it that way*. A given point should only lie within
the boundaries of whichever landuse areas are appropriate - so if it's
purely industrial, it shouldn't lie within a (larger) residential
area. Generally the main ones that make sense are overlapping
commercial and residential, to show that there are shops and housing
at the same coordinates.
