// 7.2 Native Ad Unit IDs - To Be Deprecated
//
// Ad Unit ID is to be deprecated in a future version and is not suggested for new implementations.
//
// Below is a list of the core ad unit ids described by IAB here http://www.iab.net/media/file/IABNativeAdvertisingPlaybook120413.pdf
//
// In feed unit is essentially a layout, it has been removed from the list. The in feed units can be identified via the layout parameter on the request.
//
// An implementing exchange may not support all asset variants or introduce new ones unique to that system.
