Description
A sect1 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 alternatives to the numbered sections and have unbounded depth.simplesects, which are terminal. Thesimplesects 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.
