Tags Tree Tips You Should Know

Automated accessibility checkers can flag errors, but they cannot always tell you whether a heading is tagged correctly, a nested list has the right structure, or several pages of content never entered the tags tree at all. In this episode of Chax Chat, Dax Castro and Chad Chelius explain what it means to "walk the tags tree" and why this manual review remains essential to accessible PDF remediation. They cover efficient keyboard navigation, Highlight Content, page-to-page reading order, misplaced figures, nested lists, role mapping, when to return to the source file, and why rotated tables require a different approach. They also discuss the judgment behind remediation: how to distinguish a genuine barrier from a technical imperfection and balance user impact, time, and budget without losing sight of accessibility.
