I also have a confusion around this, I read it as saying a that a 'border'
way can only represent the highest admin level, even though it (probably)
also represents the lower levels as well.

This might cause a problem if one was to scan the database to download all
the level 1 borders for an area.


Also this discussion has not questioned the use of relations to store the
boarders. This would enable shorter, more appropriate, ways to be used. A
collection of ways could be 'combined' into on relation the bounds of a
border.

Also note that borders can be areas with cut outs, for example the Town of
Pincher Creek is completely surrounded by the MD of Pincher Creek. These
are separate adminstrative areas, ie. different councils/tax bills/etc.

Cheers,
Mungewell.
