Hi all,
first of all: the import should be ready this weekend. I used the simplifier-plugin in JOSM which reduced the nodes from over one million down to about 360'000.. Handling is a lot easier now.

while we are redoing all our boundaries in Switzerland, could we maybe discuss the format of the boundary relations once more?
You mean if type=boundary or type=multipolygon? :->
boundary=*, the type tag is sooo out of fashion. ;)
In particular, I'd like to get rid of the subparts in those relations.
Lucky you, the new relations will be without hierarchy anyway, so that's a good moment to separate them. Because - as Stéphane says - it's just practical to have the hierarchy included in relations and not just the 'raw' data..
As I said, 'practical' depends on your point of view. If you try to build polygons from the relations, those are very impractical. And I know I'm fighting windmills here but may I point out once more that relations are NOT bookmarks. If you need all boundaries in Switzerland, you can use the XAPI.
Is there any accepted tagging scheme?
Looking at the boundary page in the Wiki again, it seems that somebody actually did make the subarea an official role. I checked the database now and only the Czech Republic seems to actually use this (and some smaller counties in Spain and Japan). Altogether about 6000 out of 160.000 boundary relations. On the other hand, we are also the only ones to have a relation "type=nation". So, no, there is no accpeted tagging schema, I'd say.
