Maybe you are being (or were being, cause you have already uploaded the
data with boundary=administrative) over-interpretative. I guess we don't
need a political institution in an administrative division to be
considered administrative. Just if it has administrative interest would
I've seen a total of 137 administrative divisions in Switzerland
(already counting the Basel ones) with admin_level=9, and a similar
number for admin_level=10. So my opinion is that tagging them as
boundary=administrative + admin_level=9 is the optimal solution.

The rule is that each segment should have as admin_level the highest
level of all the admin divisions it belongs to. All inner suburb
segments lacked the admin_level=9 tag, so I've just added it now .

I was meaning that boundary=suburb wasn't, afaik, documented.
But place=suburb is, althouth it's another thing (same value but for a

Although a bit off-topic, I have seen that all boundaries in Switzerland
need some corrections. When looking at level 9 entities, I checked for
example Jorat-Menthue (admin_level=8), in District du Gros-de-Vaud (6),
Canton of Vaud, that is divided in 5 admin_level=9 entities. I saw that
this Jorat-Menthue is duplicated (2 relations) . It would be nice
that an experienced user of the Swiss OSM community has a check
nation-wide to correct this and other errors.
