Headed group of material; the basic structural unit of the body of a document.


Standards documents are almost invariably divided into sections, each with a title that describes the content of the section, such as “Introduction”, “Scope”, “Normative References”, or “Terms and definitions”.

Sections are recursive, that is, various levels of sections are indicated by containment, not by different names for the subsections. A <sec> element may contain lower level sections that are also tagged using the <sec> element, not tagged explicitly as <sec2>, <sec3>, or <subsec1>, etc.

Conversion Note: The <sec> element can be used within <back> to tag material that has not been explicitly named as one of the other back matter components, that is, it is not named as an appendix, an acknowledgment, a glossary, etc. For example, tables are frequently placed in the back matter, with no other designation than a label such as “Table 6”, or a title such as “Epochs of Geologic Time”.

This element is part of the base JATS journal publishing vocabulary; its definition and documentation have been modified to reflect its use in the ISOSTS customization of JATS.
