[Geojson] RFC 7946 - composing geometry objects with "mixed" positions

[Udo Schochtert <[e-mail]>]

hi,

I have a quick question regarding RFC 7946 specs.

according
  https://tools.ietf.org/html/rfc7946#section-3.1.1
a position is an array of numbers which MUST have 2 elements and SHOULD not
extend beyond 3 elements.

so a valid Point (containing 2 elements) is
{
  "type": "Point",
  "coordinates": [100.0, 0.0]
}
and one containing 3 elements
{
  "type": "Point",
  "coordinates": [101.0, 1.0, 1.0]
}
is valid as well.

my question is if the following MultiPoint (composed by"mixed" positions)
would be valid as well

{
  "type": "MultiPoint",
  "coordinates": [
    [100.0, 0.0],
    [101.0, 1.0, 1.0]
  ]
}


that would also apply to other geometries composed by"mixed" positions as
well (e.g. LineString, Polygon, etc.). correct?

thanks, udo
