For a sample invoice, the library reports: A VAT breakdown with the VAT category code (BT-118) L (Canary Islands general indirect tax (IGIC)) must not have a VAT exemption reason code (BT-121) or reason text (BT-120), but you supplied vatExemptionReasons.L = "Exento".

BT-120 / BT-121- Severity
warning
The fix
Remove the "L" entry from vatExemptionReasons. If you need to say something to the buyer about this line, use the invoice note (BT-22) or the line note (BT-127), which carry free text without making a VAT claim.

The full error returned by @attestwire/en16931. It includes the rule ID,

{
"rule": "BR-AF-10",
"field": [
"BT-120",

],

"message": "A VAT breakdown with the VAT category code (BT-118) L (Canary Islands general indirect tax (IGIC)) must not have a VAT exemption reason code (BT-121) or reason text (BT-120), but you supplied vatExemptionReasons.L = \"Exento\". Category L charges IGIC, which is a tax actually levied on the supply — an exemption reason would claim relief from the very tax the breakdown says you collected. BR-AF-10 is fatal at document level; this finding is a warning because the library drops the value rather than emitting it, so the generated XML still passes — but your intent was silently discarded, which you should know about.",

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