What the rule checks

As the rule set's publisher wrote it. The rule runs on every element the context matches, and fails where the test is false; the validator reports the line of that element.

Context
/*:Facturae/*:Invoices/*:Invoice/*:Items/*:InvoiceLine
Test
not($euro) or ($cost = es:round($product) and es:dec(*:GrossAmount) = $gross and (every $a in $amounts satisfies es:cents($a)))

Checked with Facturae 3.2.2
