Topics are terminal, "leaf" mini-sections, like block quotes with titles, or textual figures. A topic is just like a section, except that it has no subsections, and it doesn't have to conform to section placement rules.

Topics are allowed wherever body elements (list, table, etc.) are allowed, but only at the top level of a section or document. Topics cannot nest inside topics, sidebars, or body elements; you can't have a topic inside a table, list, block quote, etc.
