UBL-CR-679

Disallowed schemeID attribute on the tax category

Repaired automatically EN16931 UBL

What it means

The EN 16931 UBL binding forbids a schemeID attribute here; the tax category identifier is drawn from a fixed code list, so naming a scheme is redundant and ambiguous.

Can it be fixed automatically?

Nothing about your business is needed to fix this — the correct value is a constant, a code list entry, or is already present in the document.

This one can be repaired automatically. The API applies the fix, re-validates, and reports exactly what changed with before and after values.

How to fix it

Remove the schemeID attribute. The identifier value itself is unaffected, so no meaning is lost.
