Allow different currencies for the price

[RafiKueng]

not only €.. CHF / SFr would be nice as well, for example for Swiss universities..

Would it be enough to be able to switch the concurrency completely? Either € or CHF / SFr and not both at a time?

I was more suggesting it to be considered for a future upgrade of the protocol.. on the long term..
It could also be that meals have prices in two currencies (here Swiss Francs and Euro)
maybe something like:

<price role="student" currency="EUR">2.00</price>
<price role="student" currency="CHF">2.00</price>
<price role="employee" currency="CHF">2.00</price>

I suggest using ISO 4217 abbr. and not the currency symbol, that should be rather a setting in the client app.
You can make it default to EUR, so it will be perfectly backwards compatible.

On short term, I don't really care what symbol is behind the price, when I write the scrapper.. But it could be confusing for others.

alternatives I all like less

<price role="student">2.00 EUR</price>
<price role="student">2.00 CHF</price>

<price role="student">
  <currency>
    <type>EUR</type>
    <amount>2.00</amount>
  </currency>
  <currency>
    <type>CHF</type>
    <amount>2.00</amount>
  </currency>
</price>

but I havent thought about it much
