Description
The objective of this technique is to show how to tag lists with at least one list item with substructure.
The complete substructure content should be included in the LBody of the related LI structure element. In this example, because two of the list items contain additional paragraphs of text, each paragraph is tagged in its own P tag, within the related LBody structure element.
