[Tagging] ATMs and cashback

[seirra]

as an example, say a cash machine dispenses £10 and £20 notes... you 
can't guarantee you'll get 20s can you? but what you do know, is you can 
get any multiple of 10. so maybe the standard notation could be that you 
put currency, the currency code, then the smallest amount you can get? 
as the smallest amount is usually meant to be able to make up any larger 
amount theoretically that should be enough. (for example, 5 would 
declare you can get anything that is a multiple of 5, 10 would declare 
anything that is a multiple of 10). so using that idea you could put 
currency:GBP=5, and that would declare it lets you get multiples of 5, 
but if you're unsure you can put currency:GBP=yes. i guess you could 
also put currency:GBP=5;10;20. there are no other cases of numerical 
uses for the currency tag, so it seems like an okay way to do it
