[Geojson] simple 3D geocode for AR

[Andrew Turner]

Simplest?

Just include a 3rd coordinate in GeoRSS-Simple point or GeoJSON point.

No, this is not explicitly valid. But you see where that discussion
gets us. Long windy roads of elusive semantic talk (arguably necessary
in the lon term, but not simple or useable *now*, which is when people
are building these tools).

If we lose interest without achieving a near term concensus,
developers will just do arbitrary, different solutions. Give them a
simple answer now, even if it makes your strict-validation-only-skin
crawl just a little bit. :)

So I say just do it, and we'll catch up with documenting it as uses
emerge.

Also, KML already supports 3D points.
