// 3.2.2 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 3.2.3), Video (Section 3.2.4), and/or Native (Section 3.2.5) 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.
