<section>
The <section> element represents an organizational division in a
         topic. Sections are used to organize subsets of information that are directly related
         to the
         topic. Multiple <section> elements within a single topic do not represent
         a hierarchy, but rather peer divisions of that topic. Sections cannot be nested. A
         <section>
         can have an optional title.
      For example, the titles Reference Syntax and Properties might represent section-level discourse within a topic about a command-line process—the content in each <section> relates uniquely to the subject of that topic.
 Note: For maximum flexibility, sections allow plain text as well as phrase
               and block level elements. Because of the way XML grammars are defined within a DTD,
               any element
               that allows plain text cannot restrict the order or frequency of other elements. As
               a result,
               the <section> element allows <title> to appear
               anywhere as a child of <section>. However, the intent of the
               specification is that <title> should only be used once in any
               <section>, and when used, it should precede any other text or element
               content.
