Document Structure
Headings, lists, tables, and reading order must be structurally encoded — not just visually styled. Applies to Word, PowerPoint, InDesign, and Google Docs. Export to tagged PDF.
In plain terms
Word, PowerPoint, and similar files need real headings and lists, not just big bold text, so they work for everyone and export cleanly.
Why this matters
A document that's only visually formatted is a wall of unstructured text to a screen reader. Real structure — headings, lists, tables — is what lets disabled users navigate Word, PowerPoint, and PDF files, and it's required by the same laws as the web.
