## Description

A `Sect2` is a second-level section in a document.

### 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 sect2: `sect1`.

## 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 `Sect2`.

  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).

## See Also

`bridgehead`, `sect1`, `sect3`, `sect4`, `sect5`, `section`, `simplesect`.
