DocBook provides a system for writing structured documents using SGML or XML (semantic markup). It is particularly well-suited to books and papers for technical documentation. Earlier versions of DocBook were formally defined as document type definitions (DTDs). From version 5.0 onwards, SGML support is discontinued and the official definition is a RELAX NG schema.
