This example lists selected data from two **TemperatureSensor** entities chosen by `id`. Note that every `id` must be
unique, so `type` is not required for this request. To filter by `id` add the entries in a comma delimited list.

A list of `id` values is not on its own enough to make a query. NGSI-LD requires at least one of `type`, `attrs`, `q`,
a GeoQuery or `local=true`, and raises `BadRequestData` ("too wide query") without one, `pick` does not count,
so`local=true` is used here because it satisfies the requirement without naming a `type`.
