And beyond. There is no change here - lists are general-purpose
constructs, and lists may contain paragraphs (and tables and lists

Yes, but it is worse than useless trick (and may seriously mislead the
user, especially if the browser displays <ins> element content as
different from normal text, as most browsers do these days).

In practical terms, there's seldom need to include the author's contact
information (which is what <address> means, by definition) inside a
paragraph. The <address> element is essentially a paragraph of a very
special case; all that a validator cares, though, is the nesting rules and
other syntax, of course.
