Signaling payment handler details errors

[marcoscaceres]

For example, the card might have expired. There might be insufficient digits, etc...

To say a bit more: suppose the merchant gets back some payment credentials and those credentials don't work for some reason. The merchant might want to prompt the user again, but "minus the unacceptable credentials". Such information would need to be passed to the payment handler as well.

[marcoscaceres]

The model in the spec is “the following things are erroneous: x, y, z.” But not “minus unacceptable”, which seems different to me.

I think there is a difference between:

• Please correct this information, and
• You can't use this, so the browser or payment handler should no longer present it as an option

I'm not in favor is this, tbh. Right now, everything maps to input fields.

We don't have this feature today and that has not been a show-stopper.

Paying for TPAC today...

We can't do this today :)

This bug should probably move to the basic card spec.

Moved https://github.com/w3c/payment-method-basic-card/issues/57

[marcoscaceres]

Reopening, because this still needs infrastructure in this spec.
