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

Follows every /RoleMap chain; reports each element and each map entry that ends in a loop.

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.
