BR-CO-15: Invoice total amount with VAT (BT-112) must match the invoice's other totals

ExampleEN 16931 (UBL)

An invoice built like a valid one, except for this:

<cac:LegalMonetaryTotal>
  <cbc:LineExtensionAmount currencyID="EUR">100.00</cbc:LineExtensionAmount>
  <cbc:TaxExclusiveAmount currencyID="EUR">100.00</cbc:TaxExclusiveAmount>
  <cbc:TaxInclusiveAmount currencyID="EUR">150.00</cbc:TaxInclusiveAmount>
  <cbc:PayableAmount currencyID="EUR">150.00</cbc:PayableAmount>
</cac:LegalMonetaryTotal>

The validator says: Invoice total amount with VAT (BT-112) is 150.00, but the other amounts on the invoice add up to 119.00.
