In Item Information (IBG-31) where Invoiced VAT category code (IBT-151) is 'Reverse charge', the corresponding Item Standard Identifier (IBT-157) must be there and the Scheme Identifier (IBT-157-1) should have the code 0160.

Fails when this is false

not(not(exists(../cac:StandardItemIdentification/cbc:ID)) or ../cac:StandardItemIdentification/cbc:ID/@schemeID != "0160")

The schematron test, verbatim. Context: cac:InvoiceLine/cac:Item/cac:ClassifiedTaxCategory[normalize-space(cbc:ID) = 'AE'][cac:TaxScheme/normalize-space(upper-case(cbc:ID))='VAT'] | cac:CreditNoteLine/cac:Item/cac:ClassifiedTaxCategory[normalize-space(cbc:ID) = 'AE'][cac:TaxScheme/normalize-space(upper-case(cbc:ID))='VAT']

Fix

Change the data so the statement above is true. Paste the invoice into the validator to see the exact element that fails.
