Description

Sect1 is one of the top-level sectioning elements in a component. There are three types of sectioning elements in DocBook:

  • Explicitly numbered sections, Sect1Sect5, which must be properly nested and can only be five levels deep.

  • Recursive Sections, which are 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.

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.

This means that you cannot have content in the Sect1 after the end of a Sect2. This is consistent with the DocBook book model, because in a printed book it is usually impossible for a reader to detect the end of the enclosed second level section and, therefore, all content after a second level section appears in that section.

Processing Expectations

Formatted as a displayed block. Sometimes sections are numbered.

Future Changes

In DocBook V4.0, the ToC element in the content model will be replaced by TocChap.

Parents

These elements contain sect1: appendix, article, chapter, partintro, preface.

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.

renderas

The RenderAs attribute identifies how the section should be rendered. In this way, a section at one level of the structural hierarchy can be made to appear to be at another level.

status

Status identifies the editorial or publication status of the Sect1.

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).
