Description

Section is one of the top-level sectioning elements in a component. There are three types of sectioning elements in DocBook:

• Explicitly numbered sections, Sect1…Sect5, which must be properly nested and can only be five levels deep.

• Recursive Sections, which are an alternative to the numbered sections and have unbounded depth.

• SimpleSects, which are terminal. SimpleSects can occur as the "leaf" sections in either recursive sections or any of the numbered sections, or directly in components.

Sections may be more convenient than numbered sections in some authoring environments because they can be moved around in the document hierarchy without renaming.

None of the sectioning elements is allowed to "float" in a component. You can place paragraphs and other block elements before a section, but you cannot place anything after it.

Processing expectations

Formatted as a displayed block. Sometimes sections are numbered.

Use of deeply nested Sections may cause problems in some processing systems.

Parents

These elements contain Section: Appendix, Article, Chapter, PartIntro, Preface, Section.

Children

The following elements occur in Section: Abstract, Address, Anchor, AuthorBlurb, Bibliography, BlockQuote, BridgeHead, CalloutList, Caution, CmdSynopsis, Comment, Epigraph, Equation, Example, Figure, FormalPara, FuncSynopsis, Glossary, GlossList, Graphic, GraphicCO, Highlights, Important, Index, IndexTerm, InformalEquation, InformalExample, InformalFigure, InformalTable, ItemizedList, LiteralLayout, LoT, MediaObject, MediaObjectCO, MsgSet, Note, OrderedList, Para, Procedure, ProgramListing, ProgramListingCO, QandASet, RefEntry, Screen, ScreenCO, ScreenShot, Section, SectionInfo, SegmentedList, Sidebar, SimPara, SimpleList, Subtitle, Synopsis, Table, Tip, Title, TitleAbbrev, ToC, VariableList, Warning.

In some contexts, the following elements are allowed anywhere: BeginPage, IndexTerm.

Attributes

Label

Label specifies an identifying string for presentation purposes.

Generally, an explicit Label attribute is used only if the processing system is incapable of generating the label automatically. If present, the Label is normative; it will used even if the processing system is capable of automatic labelling.

Status

Status identifies the editorial or publication status of the Section.

Publication status might be used to control formatting (for example, printing a "draft" watermark on drafts) or processing (perhaps a document with a status of "final" should not include any components that are not final).
