The DocBook Schema Version 5.2
OASIS Standard
06 February 2024


Almost all computer hardware and software developed around the world needs some documentation. For the most part, this documentation has a similar structure and a large core of common idioms. The community benefits from having a standard, open, interchangeable vocabulary in which to write this documentation. DocBook has been, and will continue to be, designed to satisfy this requirement. For more than 25 years, DocBook has provided a structured markup vocabulary for just this purpose. DocBook Version 5.2 continues the evolution of the DocBook XML schema.
