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 each page's own content stream (not form XObjects): a painting operator (text, path paint, shading, image, form) must sit inside an Artifact sequence or inside marked content whose MCID a structure element holds. A page with no structure tree has all its content untagged.

Repairs that target it

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