What it means
For each ram:SpecifiedAdvancePayment/ram:IncludedTradeTax, this rule counts ram:CategoryCode child elements. It requires exactly one element, but does not check its value. FX-SCH-A-000955 separately checks non-empty category codes against the permitted list.
Why it matters
The category records the tax treatment described by each entry.
How to fix it
Check ram:CategoryCode in each advance payment tax entry. Add one element if it is missing, or remove duplicates while keeping the appropriate category. For VAT, S covers positive-rate VAT, including reduced rates, while Z identifies zero-rated VAT. Export and recheck.
