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
Test
abs($outputs - sum(for $t in *:TaxesOutputs/*:Tax return es:dec($t/*:TaxAmount/*:TotalAmount) + es:dec($t/*:EquivalenceSurchargeAmount/*:TotalAmount))) le 0.01

Checked with Facturae 3.2.2
