Where the rule applies
Syntax: CII · UBL
The same rule, expressed twice: UBL and CII name the same fields with different paths. Running a CII file against the UBL rules is why you get errors that mean nothing.
UBL
//cac:InvoiceLine/cac:AllowanceCharge[cbc:ChargeIndicator = false()] | //cac:CreditNoteLine/cac:AllowanceCharge[cbc:ChargeIndicator = false()]
CII
//ram:SpecifiedLineTradeSettlement/ram:SpecifiedTradeAllowanceCharge/ram:ChargeIndicator[udt:Indicator = 'false']
