What does BR-CL-17 mean? Invoice tax categories MUST be coded using UNCL5305 code list

Why did my invoice fail BR-CL-17?

Invoice tax category codes must come from the UNCL 5305 code list (the duty/tax/fee category codes: S, Z, E, AE, K, G, O, L, M, B). This check applies to tax category codes used on the invoice so that VAT treatment is machine-readable. In UBL the element is cac:TaxCategory/cbc:ID or cac:ClassifiedTaxCategory/cbc:ID.

Official rule text

Invoice tax categories MUST be coded using UNCL5305 code list

Common causes

• A percentage or rate value placed in the category code field
• Lowercase codes ("s" instead of "S")
• Invented codes like "STD" or national category labels

How do I fix it?

<cac:ClassifiedTaxCategory>
  <cbc:ID>S</cbc:ID>
  <cbc:Percent>22</cbc:Percent>
  <cac:TaxScheme><cbc:ID>VAT</cbc:ID></cac:TaxScheme>
</cac:ClassifiedTaxCategory>
