Allowance/charge ChargeIndicator value MUST equal 'true' or 'false'
An allowance/charge indicator is not literally 'true' or 'false'.
Use lowercase true or false.
CII — context —
normalize-space(ram:ChargeIndicator/udt:Indicator/text()) = 'true' or normalize-space(ram:ChargeIndicator/udt:Indicator/text()) = 'false'
Nothing is stored, and the whole invoice is checked, not just this rule. A PDF only works if it is Factur-X / ZUGFeRD — a PDF with the invoice XML inside it.
