> **ERROR**: XRechnung 3.0

## Context and Significance

A document-level allowance in the export breakdown cannot carry VAT, so its rate must be zero to keep the category G breakdown VAT-free.

## Solution

Set the allowance TaxCategory/cbc:Percent (BT-96) to 0 whenever the document level allowance category is G.

- validate
- convert

## Valid Examples

- Document allowance with BT-95 = G and BT-96 = 0
