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
exists(//ubl:Invoice/cbc:TaxCurrencyCode | //cn:CreditNote/cbc:TaxCurrencyCode) and normalize-space(@currencyID) != $bt06
