transfer, as an InfoSet after transfer to a CompositeProvider returns a
different 0INFOPROV. The most left PartProvider of a CompositeProvider
supplies 0INFOPROV.

(exchange right and left join PartProvider), or to use a referencing
InfoObject instead of the basic characteristic, Materialize the data in
another InfoProvider and use this.
