Test
every $Currency in cbc:DocumentCurrencyCode satisfies (count(//cac:TaxTotal/xs:decimal(cbc:TaxAmount[@currencyID=$Currency])) eq 1) and (cac:LegalMonetaryTotal/xs:decimal(cbc:TaxInclusiveAmount) = round( (cac:LegalMonetaryTotal/xs:decimal(cbc:TaxExclusiveAmount) + cac:TaxTotal/xs:decimal(cbc:TaxAmount[@currencyID=$Currency])) * 10 * 10) div 100)
