Yes, I meant bounding box. Perhaps my original proposal of "extent" is
more accurate: extent as in "geographic extent covered by this
90% of cases this will be a rectangle, but as Tim pointed out there
are special cases. As for the points, I suspect that in quite a few
cases this extra will be filled via a geolocation service, which
generally return point coordinates (i.e. people won't bother to find
the exact bounding box for the "London" city limit polygon). As I
mentioned before, I'm more interested in agreeing their names than
their contents.

Stefano, Tim, any thoughts on how would you name the three extras?

As for the 5MB GeoJSON, I'd expect a little common sense from the user
in the same way people does not paste 10 pages of text if the notes
