Hi

Decimal separators need a another look. For example, in #99, https://schema.org/price says "Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator." But such guidance is not given for other numeric properties such as https://schema.org/ratingValue . I would argue ratingValue is as important as price as they're usually found together.

One approach is to write such guidance when a numeric property is of the type Text, but also add specific instructions on https://schema.org/Number saying to use decimal points as the separator and commas for groups as per current standards (Wikipedia ref).

Thanks.
