Re: [browser-payment-api] Different card schemes have different mandatory field requirements (#9)

I am happy to defer to the editors, but it would be nice if FPWD was able to accommodate China in its basic card model. That being said, I appreciate time is of the essence so maybe a commitment to resolve the issue in a future draft is enough.
