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.

Test
cbc:TransactionCurrencyTaxAmount and (number(cbc:TransactionCurrencyTaxAmount) != 0) and (cac:TaxCategory/cbc:ID = 'StandardRated') and (((number(cbc:TransactionCurrencyTaxAmount) < 0) and (number(../cbc:TaxAmount) > 0)) or ((number(cbc:TransactionCurrencyTaxAmount) > 0) and (number(../cbc:TaxAmount) < 0)))
