Re: [w3c/payment-request] Permissible data changes during a retry (#933)

Thanks for the response!
>That is correct... say the user wants to ship something to post code "1234", but the merchant says, "Post code 1234 is not valid". The user realizes that the entire address is wrong, and because of that, they decide to pay with an entirely different card. That's totally ok.

Ok, thanks for the clarification - that's the way I understood the spec as well.

> Just to make sure we are on the same page, is the example I gave above what we should try to clarify in the spec?

No, I think that's clear from the spec (although an example might be helpful in making that more explicit). I was just confused/unsure about my understanding due to your comment in #882 that "One can only change the things being retried".

I.e., my understanding of the spec is that the user agent may allow changes to, e.g., the credit card data even if the reason for the retry was an invalid shipping address. If that understanding is correct, we can close this issue :slightly_smiling_face:
