Description
# What is the name of the object containing the coordinate attributes?
https://github.com/mapbox/geojson-coordinate-properties puts the coordinate properties in a special property, `properties.coordinateProperties`.
The current Tippecanoe implementation puts them in `geometry.attributes`.
# Is the object flat or structured?
https://github.com/mapbox/geojson-coordinate-properties and Tippecanoe use nested arrays for the coordinate attributes of nested geometry types like MultiLineString
http://github.com/mapbox/vector-tile-base uses a flat structure, as does the vector tile representation

Research direction
Compare the coordinate-property representations described in geojson-coordinate-properties, Tippecanoe, and vector-tile-base. Start by identifying the current vector-tile specification section for geometry attributes; done requires a settled specification for the containing object and whether nested coordinate attributes are flat or structured.
