Checkpoint

28: Annotations

ISO 14289-1 (PDF/UA-1) clause

7.18.3-1

Test type in the protocol

Machine-testable

Applies to

A single object

WCAG 2.x (AxisRemedy's informative mapping)

2.4.3 Focus Order (level A); 1.3.2 Meaningful Sequence (level A)

How AxisRemedy handles it

Tested by the app. AxisRemedy tests this condition itself. For each document it records passed, failed or not applicable, and for every failure the object and the page.

What the check covers

Tests pages whose /Annots array holds at least one dictionary. Not tested on a page with no /Tabs entry.

Repairs that target it

• Tab order follows the structure on pages with annotations

Repairs are optional. The few that could change how a page looks, such as embedding a missing font, need your explicit consent.
