do not assign categories to boundaries unless you really need them. consider two blocks of land next to each other, separated by a single boundary. To which block of land does the boundary belong to? Neither. So it has no cat and a centroid in each block contains that information (along with associated database things like owner, etc.) the rare exception is when the boundary which separates them is a road, and you want that road to have its own attributes (like pavement type, highway number, number of lanes, etc.)\ type="area" is really a bit of an alias for boundary + its centroid.
