Sure, but to define a UI element which forces currency conversion
capabilities on server side code is too onerous. it would require
servers to have a foreign exchange rate mechanism which inevitably
requires further external service calls in order to remain up to date.

For each of the example sites, they would be able to use currency
inputs in order to manage formatting and symbol/code display while
still integrating with their back-end forex to provide their more
advanced service capabilities.
