Version 5.2 is fully ready for testing and implementation
OASIS is pleased to announce that The DocBook Schema Version 5.2 from the OASIS DocBook TC  has been approved as an OASIS Committee Specification.
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.
This Committee Specification is an OASIS deliverable, completed and approved by the TC and fully ready for testing and implementation.
