Explain one EN 16931 / XRechnung / Peppol BIS rule in plain English: what it requires, why, the business term it constrains, a concrete fix and an example. 270 rules explained — BR-*, BR-CO-*, BR-<category>-*, BR-DE-* and PEPPOL-EN16931-*. That is most, not all, of what the validator checks: a few arithmetic/decimal rules have no write-up yet, and for those it says so and links the rule reference rather than pretending the rule does not exist. FREE and needs no API key.
