Ok, this didn't really work. I tagged the donut hole as an "outer" role in Orange county - an outer within an outer - and the shared border shows "Orange County Westminster" together on the outside of the donut hole. I would have imagined the OC being on the inside of the border. What it looks like now: http://www.openstreetmap.org/#map=19/33.73459/-117.98256&layers=N I guess I should undo these experiments and leave it alone.

It is not necessary but may add clarity for people editing the data. Generally it is recommended to tag boundary=administrative, admin_level=<highgest admin level involved>, and no names (no county:left, county:right stuff etc either). > Within Westminster is a "donut hole" , and the Westminster relation > has it as a role=inner. > > Question: should that same donut hole be tagged role=outer in the > Orange County relation? Yes, that's what I would suggest. It would be nice if our tools allowed you to simply make the Westminster *relation* an "inner" of Orange county and thereby automatically do the donut justice but that's not supported by anything really. > It just doesn't feel right to have a role=outer fully within another > role=outer, but that's the only way I can think of to handle this. Rest assured, when you hear Mathematicians talking about geometry, they will happily accept that an outer ring can be surrounded by an inner ring.
