Re: [webpayments] What is the use case for the Payment Details object? (#38)

@mountainhippo In our flow, the expectation is that payment apps do not communicate with PSPs. I mean, technically there is nothing stopping them, but it's not expected. The expected flow is the merchant still submits the payment credentials that came back from the payment app to their PSP for processing. At that time, *if* it's required, they could send item information in with that request. That said, I agree with Manu that this is not something we should be encouraging.
