Struct WitnessQuestionId 

pub struct WitnessQuestionId(/* private fields */);

A question’s number among the questions the seats put to an item’s witnesses: 3 (0.104)

Numbered from 1 in the order asked, across every witness on the item, so a seat can name a question it asked and the record can find it in the batch it was sent in. One form everywhere: the bare number, in the batch the witness reads (3.), in what a seat is told, and in the record (the JSON number 3).
