Missing latest_receipt and latest_receipt_info definition in IAPResponseForIOS6?

[richzw]

Per this doc

`latest_receipt

Only returned for receipts containing auto-renewable subscriptions. For iOS 6 style transaction receipts, this is the base-64 encoded receipt for the most recent renewal. For iOS 7 style app receipts, this is the latest base-64 encoded app receipt.

latest_receipt_info

Only returned for receipts containing auto-renewable subscriptions. For iOS 6 style transaction receipts, this is the JSON representation of the receipt for the most recent renewal. For iOS 7 style app receipts, the value of this key is an array containing all in-app purchase transactions. This excludes transactions for a consumable product that have been marked as finished by your app.`

However, I cannot find those two fields defined in IAPResponseForIOS6?
