Geojson is not a XML format, but you are right, the colums names are
repeated for each features :
https://en.wikipedia.org/wiki/GeoJSON
http://www.geojson.org/

I have not yet search how we could build a spatial index from a GeoJSON,
but we surely could find a way.
It supports GZIP compression, as it is a simple text file,  and we could
use it as QGIS can now handle zipped files.

You are right, but I am looking for an open-source format. :)
