Collection bbox schema

[drwelby]

The definition of the bbox spatial extents has non-obvious construction:

The first bounding box always describes the overall spatial extent of the data. All subsequent bounding boxes can be used to provide a more precise description of the extent and identify clusters of data.

i.e.
[[extent]] or [[extent], [child], [child]...]

Should the schema try to catch people interpreting the spec as a simple list of bboxes by enforcing either a length of 1 or 3?

Or is that too restrictive and the catch should be passed down to validators like stac-check?

We could add reference to the same spec as geojson RFC for items.

Yeah, that makes sense. Two bboxes don't make sense.

So either one or 3 or more.
