List elements (in particular, and elements) cannot be children of elements. When a sentence contains a bulleted list, therefore, one might wonder how it should be marked up. The solution is to realize that a paragraph, in HTML terms, is not a logical concept, but a structural one. In the fantastic example above, there are actually five paragraphs as defined by this specification: one before the list, one for each bullet, and one after the list. The markup for the above example could therefore be: Authors wishing to conveniently style such "logical" paragraphs consisting of multiple "structural" paragraphs can use the element instead of the element. Thus for instance the above example could become the following: This example still has five structural paragraphs, but now the author can style just the instead of having to consider each part of the example separately.
