Error 3

E3: Check that priceSpecifications are non-overlapping in terms of quantity. i.e. None ranges min-max values in price specifications are include in others

Note: This validation must be done before E4

Validator Tool: Step # 3

Error Message

None ranges min-max values in price specifications are include in others

Potential Problem

One offering (gr:Offering) can include more than one price specification. Prices specifications can include price intervals using the gr:hasMinCurrencyValue - gr:hasMaxCurrencyValue properties. Care must be taken that price ranges in price specifications for the same offering do not overlapp to each other.
