XSD is a tool for anyone working with the Italian FatturaPA electronic invoice format — accountants, consultants, developers, SMBs — who needs to validate invoices on the go. WHAT IT DOES Real XSD validation. The XML is checked against the official Italian Revenue Agency (Agenzia delle Entrate) schema and every error is reported with the exact line and column: missing required elements, values that do not match the expected pattern, wrong element ordering. No "well-formed and you're done". Both official schemas bundled: FatturaPA ordinary v1.2.2 and FatturaPA simplified v1.0. The correct one is detected automatically from the XML namespace — you never have to choose by hand. Support for signed .p7m files (CAdES-BES). The PKCS#7 container is opened automatically and the embedded XML is validated like a regular .xml. Most real invoices arrive signed, and most phone tools cannot open them — this one can. Digital signature check at two levels: • Cryptographic validity — content digest and RSA signature are recomputed with the signer certificate's public key. If a single byte has been changed after signing, the app flags it. • System trust — the certificate is evaluated against your device's root CA store (the same one Safari uses). Important transparency note: the app does NOT check inclusion of the certificate in the official Italian Revenue Agency Trust List (Italian TSL, ETSI TS 119 612). That administrative check is distinct from cryptographic validity and requires an online channel to AdE. Readable invoice preview using the official Agenzia delle Entrate stylesheet (the same one used on the FatturaPA portal), with PDF export via the iOS share sheet. Generic XML mode. Use any custom XSD to validate any XML, beyond the FatturaPA world. "Open in XSD" from Mail, Files, AirDrop and any other app: .xml and .xml.p7m files are loaded directly. OFFLINE AND PRIVATE Everything happens on the device. No uploads, no account, no telemetry. Your invoices never leave your phone. NOT A REPLACEMENT FOR • Transmission to SDI (requires an accredited channel). • Legal long-term archival (requires a dedicated service). • Administrative validation against the official TSL. XSD is a check-and-verify tool, not a management system.
