<ConsumableInformation> <Product ProductId="2" TransactionId="00000000-0000-0000-0000-000000000000" Status="Active" /> </ConsumableInformation>
Unfortunately, it wasn't documented, so I had to work it out with the program manager who owned it. Put simply, the ConsumableInformation is used to provision a default in-app offer similar to how durable offers are included in the LicenseInformation node.
The TransactionId attribute is required, and will match the value used when calling CurrentAppSimulator.ReportConsumableFulfillmentAsync(productId, transactionId).
Status is also required, and can be Active, PurchaseRevoked, PurchasePending, and ServerError. This allows a developer to emulate all the possible responses to the ReportConsumableFulfillmentAsync call.
There is an optional attribute OfferId on the <Product> element which can be used to set the same value that would normally be set at the time of purchase for the large catalog API: CurrentAppSimulator.RequestProductPurchaseAsync(productId, offerId, displayProperties).
Fortunately, we were able to get all this into the CurrentAppSimulator documentation, which you can find here: http://msdn.microsoft.com/en-us/library/windows/apps/windows.applicationmodel.store.currentappsimulator.aspx
