The element "VAT category rate" (BT-119) shall be provided.
The VAT category rate (BT-119) is missing from a VAT breakdown group. XRechnung requires it even where EN 16931 would let you omit it.
Add BT-119 to every BG-23 group as a percentage number - 19, 7, or 0 for zero-rated, exempt and reverse-charge groups.
