Success Criterion 1.3.1 "Info and Relationships" is a Level A requirement under the "perceivable" principle of WCAG 2.2. EN 301 549 clause 9.1.3.1 maps this criterion for procurement conformance.
Correct: <ul><li> for lists, <th scope="col"> for header cells, <label for> for inputs. Incorrect: div-soup styled to look like a table — visuals carry structure assistive tech cannot see. The most-failed structural criterion on the web: if the relationship is only conveyed visually (position, grouping, font size), it fails.
Engine coverage: partially automated (audit tier 1) — automated findings flag candidates; a clean VPAT claim still needs the documented manual check.
