ATAG/ A-tag /
ATAG (Authoring Tool Accessibility Guidelines) is a W3C standard, currently at version 2.0, defining accessibility requirements for authoring tools — content management systems, page builders, IDEs, editors — both for use by authors with disabilities and for producing accessible output.
About ATAG
Published 2015. ATAG 2.0 has 24 success criteria in Part A (accessible authoring) and 27 in Part B (production of accessible content). Less widely referenced in law than WCAG; influential in CMS accessibility design.
