L_06 List with semantic images as bullets correctly tagged

PDF132, PASS

Use case(s): List

Last updated on November 20, 2025

Description

The objective of this technique is to show how to tag a list when graphical elements with a clear semantic role are used as labels for the list items.

In this example, each Lbl tag contains a Figure tag which then contains the appropriate graphic. Each Figure tag includes an appropriate Alt text, in this case "broccoli" or "tomato" as appropriate. Because the ListNumbering attribute is not required, it is not set, defaulting to a value of "None".

These minimal examples are designed to express a single Technique. Effective use requires software that supports Tagged PDF.

Expected Results

Checks #⁠1 to #⁠7 are all true.

Procedures

Check that all fundamental techniques are followed.
Check that all real content that the author intends as a list is tagged as a list.
Check that list tags are not used when the author does not intend a list.
Check that the substructures of all L tags are semantically appropriate (LI, Lbl, LBody).
If the ListNumbering attribute is used on one or more L tags in an unordered list, check that it is correctly set to "None", "Circle", "Disc" or "Square".
If graphical elements with a clear semantic role are used as the labels in a list, verify that these graphics are tagged in Figure tags with appropriate Alt text.
If graphical elements with a clear semantic role are used as the labels in a list, ensure that their Figure tags are children of Lbl tags.
