I think this could be quite useful, although I don’t know if it will get
adopted. If any such small local exchanges want to weigh in on this proposal,
that would help. Same goes for shopping cart integrators, e.g. the folks

currencyCode and cryptoCurrencyCode seem to assume that merchants will
always want to sell for fiat. But a merchant might want to sell for
another cryptocurrency instead.
Why not make it more generic, like buySymbol and sellSymbol?
