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
/cfdi:Comprobante/cfdi:Impuestos/cfdi:Traslados/cfdi:Traslado
Test
count(../cfdi:Traslado[@Impuesto = $tax and @TipoFactor = $factor and mx:dec(@TasaOCuota) = $rate]) = 1
