XML

Authorised local XSD · engine boundary

The original AT schema requires XSD 1.1 and cannot run in our existing XSD 1.0 engine. It remains NOT EXECUTED; assertions are never removed. This optional input supports authorised XSD 1.0 test or custom schemas only, with supplied-schema scope.

Public access, BYO and runtime use do not grant rights. Supply each original artifact only with concrete sufficient local processing rights, provenance and notices. No official schema is bundled or downloaded automatically.

Know what was checked

Separate statuses for XML, supplied XSD, independent business rules, plausibility and unchecked context. Unknown versions or profiles never receive complete green approval.

NIF: nine digits and checksum; domestic counterparty checks only with PT address, generic consumer ID separately. No registration proof.
Accounting: date interval, periods 1–16, transaction debit/credit balance, entry counts, section totals and account references.
SalesInvoices: dates, unique documents/lines, customer/product references, debit/credit choice, net/tax/gross and section totals excluding cancelled amounts. Simple percentage tax estimates are plausibility only.
ATCUD shape only; sentinel 0 and external correction references need context. Signature/hash chains, AT certification/SVAT, accounting truth, legal suitability and filing acceptance remain unchecked. No automatic repairs.

MovementOfGoods, WorkingDocuments and Payments business checks are outside this lite scope. Polish JPK and Romanian D406 schemas are incompatible with Portugal SAF-T.

The same version label can identify different bytes. Reports pin this reference hash and record every supplied artifact separately. Matching bytes grant no license. OECD general terms do not automatically cover AT adaptations; commercial redistribution permission remains unproven.
