WCAG 3.0 is an active W3C Working Draft in development by the AGWG. Requirements, assertions, the conformance model and reporting tiers are still being developed and may change. The latest published draft is the 10 September 2026 Working Draft; this site follows the editors’ draft, which also includes exploratory provisions.
An organisational assertion: the organisation states that it has a style guide covering image text alternatives, plus a policy or process requiring it to be followed.
Why It Matters
Alt text is written by many hands over time. A style guide is what keeps it purposeful rather than decorative or duplicative.
