// 3.2.4 Object: Imp
//
// This object describes an ad placement or impression being auctioned.
// A single bid request can include multiple Imp objects, a use case for which might be an exchange that supports selling all ad positions on a given page.
// Each Imp object has a required ID so that bids can reference them individually.
//
// The presence of Banner (Section 3.2.6), Video (Section 3.2.7), and/or Native (Section 3.2.9) objects subordinate to the Imp object indicates the type of impression being offered.
// The publisher can choose one such type which is the typical case or mix them at their discretion.
// However, any given bid for the impression must conform to one of the offered types.
