Error 20

E20: Check that all xsd:float values (in particular those attachedto gr:QuantitativeValueFloat and all price info) is compliant with the xsd:float spec.

Validator Tool: Step # 32

Error Message

Float values must be compliant with the xsd:float spec. Particulary, float values should contain only digits (no currency characters etc.) and not thousand separators (comma) and at max one dot. So "$2,019.60" is incorrect. e or E for exponents would be allowed if preceded and followed by digits. So "1234.4E07" is valid.

Potential Problem

Care must be taken that all xsd:float acomplish to the xsd specification. In particular that it contains only digits (no currencycharacters etc.) and not thousand separators (comma) and at max one dot.So ""$2,019.60"" is incorrect. e or E for exponents would be allowed ifpreceded and followed by digits "1234.4E07" is valid.
