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
/ubl:Invoice | /cn:CreditNote
Test
(exists(//cac:ClassifiedTaxCategory[normalize-space(cbc:ID) = 'NG'][cac:TaxScheme/normalize-space(upper-case(cbc:ID))='GST']) and (not(//cac:AccountingSupplierParty/cac:Party/cac:PartyTaxScheme[cac:TaxScheme/(normalize-space(upper-case(cbc:ID)) = 'GST')]/cbc:CompanyID) and not(//cac:TaxRepresentativeParty/cac:PartyTaxScheme[cac:TaxScheme/(normalize-space(upper-case(cbc:ID)) = 'GST')]/cbc:CompanyID) and not(//cac:AccountingCustomerParty/cac:Party/cac:PartyTaxScheme[cac:TaxScheme/(normalize-space(upper-case(cbc:ID)) = 'GST')]/cbc:CompanyID))) or not(//cac:ClassifiedTaxCategory[normalize-space(cbc:ID) = 'NG'][cac:TaxScheme/normalize-space(upper-case(cbc:ID))='GST'])
