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.
See appendix for information about this element in OASIS document type shells.
