PEPPOL-EN16931-R055 The VAT total and its accounting-currency amount must share a sign
noun · Peppol BIS · fatal · BT-110 / BT-111
For a sample invoice, the library reports: The invoice total VAT amount (BT-110) is 285.00 EUR and the same total in the VAT accounting currency (BT-111) is -3200.00 SEK. The two must carry the same operational sign, because they are one figure expressed twice — an exchange rate scales a number, it never flips it.

fatal
The fix
Set taxAmountInAccountingCurrency to the computed VAT total converted at the rate your tax authority prescribes for the tax point, keeping the sign: 285.00 EUR converts to a figure with the same sign, never the opposite one.

xpath is always a UBL path. On a CII invoice, look for the
matching CII field instead.
