Thanks Martin. Yes I did look at these. NONE of them have a wiki page, nor
does the residential=* tag in general, so I'm at a loss to work out what is
intended by them!

* Surely the rural/urban distinction is judged by location? Could you have
residential=rural in the town centre? Maybe (since the tag isn't
documented) but I would guess not. So what's the tag for? Does it designate
context, building style, building density...?

* Surely apartments/detached/single_family should be properties of the
building objects?

* residential=garden I quite like, but it seems to duplicate leisure=garden
and it seems strange to me to consider gardens as "residential" since
usually no-one lives in the garden. I wonder if it was ever discussed much.

* residential=gated I like. In theory you can use barrier=* and access=* to
indicate the unusual access constraints for gated residences, but actually
it's not always obvious as that, since non-gated communities might also
have fences etc. So this tag seems to me like it might make a useful

So if not self-explaining, what misunderstandings of
"residential=university" could happen? It seems quite self-explaining to
me, so I'd be grateful if you could offer your perspective of potential
misunderstandings of "residential=university".

Understood. For the building, at least, the subtag works, if used to
indicate building typology.

In British English this seems to me to  "detached" vs "semi-detached" vs
"terrace" (though there's not a 1:1 concept match). Again, though, it's not
clear to me why you'd want to tag residential areas as having these
properties, since they're already commonly indicated via the tags/geometry
of the building objects.

Thanks again for your detailed reply.
