[i18n-activity] ISO 4217 note commentary (#1045)

aphillips has just created a new issue for https://github.com/w3c/i18n-activity:

== ISO 4217 note commentary ==
5. PaymentCurrencyAmount dictionary 
https://www.w3.org/TR/2020/CR-payment-request-20201203/#paymentcurrencyamount-dictionary

> Efforts are underway at ISO to account for digital currencies, which may result in an update to the [ISO4217] registry or an entirely new registry. The community expects this will resolve ambiguities that have crept in through the use of non-standard 3-letter codes; for example, does "BTC" refer to Bitcoin or to a future Bhutan currency? At the time of publication, it remains unclear what form this evolution will take, or even the time frame in which the work will be completed. The W3C Web Payments Working Group is liaising with ISO so that, in the future, revisions to this specification remain compatible with relevant ISO registries. 

Currencies are occasionally issues, withdrawn, replaced, etc.: this note implies that ISO4217 is "stable" in terms of code assignment. ISO4217 *is* stable from the point of view that they never withdraw codes, leading to some countries having multiple codes for different time periods. The note here seems to be allowing for non-standard usages (which have become necessary due to non-governmental digital currencies). Perhaps make the situation clearer. Non-standard usage in particular seems like a Bad Idea.
