Talk:Key:non existent levels

non existent levels in the US

The common non existent level in the US, I think, would be 13. However because in the US we refer to the ground floor (`level=0`) as "the first floor", the "thirteenth floor" would be `level=12`. Looking at taginfo, I don't see any 12.

Assuming I have this right, could you add a reminder for the US, that `level=12` is what we probably want?

Alternately: it would make sense to me for `level` to refer to a zero-indexed "physical" level, while `level:ref` refers to the "colloquial" level. Which means "non existent levels" would be better called "non existent level refs". And then even in the UK, `level=13` would still exist, but it would be `level:ref=14`, and then `level=14 level:ref=15` and so on. But looking through the Wikis, I don't think this is how levels work.
