Best practice #3 introduces itself as:
> Providing locale parameters helps humans and computer applications to
work accurately with things like dates, currencies and numbers that may
look similar but have different meanings in different locales.
But the actual best practice is to use **locale-neutral**
representations that are interpreted/displayed to end-users in a
locale-appropriate manner. For example, instead of storing the string
"€2000.00", exchanging a data structure like the following is strongly
preferred:
```
"price" {
"value": 2000.00,
"currency": "EUR"
}
```
The date examples given are all in xsd:date format, which is an
excellent example of using a locale-neutral format.
Many things are dependent on locale: decimal symbol, grouping symbol,
number of grouping digits, digit shapes, etc. It's because there can be
wide variation (sometimes open to misinterpretation) that sending a
locale neutral format is preferred for data values. Note also btw that
the position of the currency symbol is dependent on the locale. In
France it would be normal to write 2000.00 € rather than €2000.00. Same
even when talking about USD when using $, ie. 2000.00 $.
