Could you build this?
Partial Writing a PDF accessibility validator that outperforms industry tools like PAC requires deep, low-level mastery of the ISO 14289 (PDF/UA) and ISO 32000 specifications and internal PDF structure trees.
What it would actually take: The application requires a low-level PDF parsing engine (in Rust or C++, compiled to native or Wasm) that traverses PDF logical structure trees (StructTreeRoot, Marked Content, BBox tagged elements) and validates reading order against WCAG 2.1 and PDF/UA standards. It demands deep domain expertise in PDF object streams and accessibility assistive technology protocols.
