- The deadlines page marks an announced Verifactu delay as pending publication and keeps the listed dates tied to BOE and AEAT sources.
Field notes
The validator is described as checking Facturae or UBL XML against the official schema and EN 16931 rules, while the deadline checker returns obligations based on answers to a short questionnaire. For QR generation, the page offers downloads in SVG or PNG. Its schedule links to official sources and separates current listed dates from an announced delay that, according to the page, had not yet been published in the BOE.
