When producing a tagged PDF (see Creating a Tagged PDF), .req files using List/ListItem elements are properly tagged to support assistive technologies to allow users to navigate from list to list or list item to list item. The following list element tag structure types are used:
L - List tag, which contains one or more LI tags.
LI - List Item tag. List item tags can contain Lbl and LBody tags.
Lbl - List item label. Contains distinguishing information such as an item number or bullet character.
LBody - List item body. Contains list item content, or for nested list, may contain additional List tags.
