        "content": "No \u2014 it\u2019s not \u201cUAA\u201d but **PDF/UA** that\u2019s the standard commonly used for PDF document remediation and accessibility. Here\u2019s a breakdown:\n\n---\n\n### What is PDF/UA?\n\n- PDF/UA stands for *PDF/Universal Accessibility*. It\u2019s an **ISO standard** (ISO 14289) specifically for making PDF documents accessible to people with disabilities, especially those using assistive technologies like screen readers. ([en.wikipedia.org](https://en.wikipedia.org/wiki/PDF/UA?utm_source=openai))  \n- PDF/UA-1 (based on PDF 1.7) and PDF/UA-2 (based on PDF 2.0) are versions of the standard, with UA-2 being more recent and adding support for new features. ([complyloft.com](https://www.complyloft.com/accessibility/pdf-ua?utm_source=openai))\n\n---\n\n### What PDF/UA Requires\n\nIn order for a PDF to be considered compliant, several specific technical requirements must be met:\n\n- The document must be **tagged** (headings, paragraphs, lists, tables, etc.), with correct semantic roles for all content. ([nutrient.io](https://www.nutrient.io/blog/what-is-pdf-ua/?utm_source=openai))  \n- Reading order must be clearly defined in the tag structure \u2014 not inferred from layout. ([nutrient.io](https://www.nutrient.io/blog/what-is-pdf-ua/?utm_source=openai))  \n- Every meaningful non-text element (images, charts, illustrations) must have **alternative text**, and decorative content should be marked as an artifact so it's ignored by assistive tools. ([nutrient.io](https://www.nutrient.io/blog/what-is-pdf-ua/?utm_source=openai))  \n- Tables should have clear header/data cells, with correct relationships; forms need properly labeled fields and logical tab order. ([nutrient.io](https://www.nutrient.io/blog/what-is-pdf-ua/?utm_source=openai))  \n- Document metadata including language, title, and bookmarks should be declared. Any security settings must allow assistive technologies to read content. ([nutrient.io](https://www.nutrient.io/blog/what-is-pdf-ua/?utm_source=openai))\n\n---\n\n### How PDF/UA Relates to Other Standards\n\n- **WCAG (Web Content Accessibility Guidelines)** covers digital content more broadly \u2014 PDF/UA is specifically about how PDFs should be structured so that they *conform* to WCAG requirements when those requirements apply to PDF files. ([accessible-docs.com](https://accessible-docs.com/overview-pdf-ua-standard/?utm_source=openai))  \n- Many regulatory frameworks (Section 508 in the U.S., European directives, etc.) require or reference both WCAG and/or PDF/UA for accessible documents. ([nutrient.io](https://www.nutrient.io/guides/pdf-ua-compliance/?utm_source=openai))\n\n---\n\n### Is \u201cUAA\u201d a Thing?\n\nIt seems likely there was a typo or mix-up \u2014 \u201cUAA\u201d does appear in some contexts (e.g. \u201cUse Attainability Analysis\u201d by the EPA), but it is *not* the acknowledged standard for PDF accessibility. ([epa.gov](https://www.epa.gov/wqs-tech/use-attainability-analysis-uaa?utm_source=openai))\n\n---\n\nIf you want, I can pull up some official governmental or institutional guidelines that list PDF/UA explicitly, or compare PDF/UA to some alternative approaches people use for document remediation."
