I'm not sure what you're trying to say. Does the photo represent your notion
of a lowered, ramp(ed), or dropped kerb? To me they're all functionally
equivalent, meaning they are wheelchair accessible and have a slight (~3cm)
abrupt change in height and/or a ramp/slope between surfaces of two
different heights (typically a sidewalk and a street).

2) "raised" is not the same as "normal" (and normal might differ a lot

I'd suggest reading the talk page, as I mentioned that the UK "raised" is
equivalent to the US "normal". And adding heights are impractical for most
people, though it is an option with kerb:height. Also if you read back in
this list discussion (Thu, Jun 23, 2011 at 12:27 AM) I talked about how a
single height is not sufficient to describe a kerb, but you must also
consider the design (e.g. slope). That's why it's best to stick to
functional definitions (i.e. wheelchair accessible).

Sounds good to me.
