L_10 Inline List correctly tagged

PDF136, 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 that occurs within a paragraph of text.

In this first paragraph the P tag contains, in addition to paragraph text, a list of items. The L tag is therefore a child of the P tag. As the list is unordered and does not include labels, it does not include a ListNumbering attribute.

In the second paragraph the ordered list requires a ListNumbering attribute set to LowerRoman.

Check that the substructures of all L tags are semantically appropriate (LI, Lbl, LBody).
Check that the ListNumbering attribute on all L tags in ordered lists is correctly set to "Decimal", "UpperRoman", "LowerRoman", "UpperAlpha" or "LowerAlpha".
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".
For those list items that include nested lists, check that the nested list’s L tag is a child of the LBody of its containing list item.
For inline lists, check that the Placement attribute is set at L, LI, Lbl and LBody to Inline.
