Reverse charge VAT breakdown tax amount must be zero

This is the rejection, word for word: „[BR-AE-09] The VAT category tax amount for reverse charge must be 0. Since reverse charge means buyer accounts for VAT, the seller's VAT amount is always zero.“

XPath: /Invoice/cac:TaxTotal/cac:TaxSubtotal[cac:TaxCategory/cbc:ID="AE"]/cbc:TaxAmount (BT-117). When BT-118 (cbc:ID in TaxCategory) is "AE" for reverse charge, the tax amount (BT-117) must be 0. This is the document-level VAT breakdown, not line-level.
