GRValidator Implemented E1

Error 1

E1: For all intervals: Check that Max<=Min (for quantitative properties and for currencyValue)

Validator Tool: Step # 1

Error Message

All maximun values must be greater than minimun values, including currencies.

Potential Problem

Prices and quantitative product properties can be specified as intervals using the gr:hasMinValueFloat - gr:hasMaxValueFloat, gr:hasMinValueInteger - gr:hasMaxValueInteger and gr:hasMinCurrencyValue - gr:hasMaxCurrencyValue properties. Care must be taken that the "min" values are lower or equal to the "max" values.
