Natural language for text in E attribute shall be determined
The document needs a correct tag tree (structure). The reliable way is to export from the authoring application with “tagged PDF” / “document structure tags for accessibility” enabled; otherwise the tags are corrected in a PDF editor.
Upload the PDF: veraPDF lists every failed PDF/UA-1 rule, our fix runs, and veraPDF checks the fixed file again — you see “N failed rules before → M after” before deciding. The fixed file costs 19 € (excl. VAT); the check is free. We never call a file “accessible” or “compliant”.
