Re: [w3c/payment-request] remove currencySystem member (#694)

Might be more accurate to say (small nit fixes):

> Implementations currently expect currency codes to be well-formed 3-letter codes as defined by ECMAScript’s “isWellFormedCurrencyCode” algorithm. Implementations will therefor allow the use of well-formed codes that are not recognized currency codes from the ISO 4217 list such as XBT, XRP etc. If the provided code is a recognized currency then implementations MAY provide additional UI hints such as appropriate symbols in the user interface.

We are continuing to evolve the standard as we gain experience as to how it’s going to be used. 

But it would be really helpful to this discussion to see examples of retailer’s websites that use points/alternative currencies that they themselves don’t control. A few screenshots would really help!
