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:Conceptos/cfdi:Concepto
Test
not(@ObjetoImp = ('01', '03', '04', '05') and $imp)

Checked with CFDI 4.0
