OASIS Members and other interested parties,
OASIS is pleased to announce that The DocBook Schema Version 5.0.1 from the OASIS DocBook TC  has been approved as an OASIS Committee Specification.Â
DocBook is widely used in computer hardware and software documentation in both commercial and Open Source environments. Broadly, this includes both print and online tutorial and reference documentation as well as online help, user guides, exercises and other ancillary forms of documentation.
The DocBook Version 5.0 schema was delivered in 2009 using the RelaxNG schema language with additional constraints specified in Schematron. The Schematron rules changed after DocBook 5.0 was released, so some Schematron tools do not work with DocBook 5.0. The DocBook 5.0.1 specification is updated with the new Schematron rules so users can continue using DocBook 5.0 if they need to use newer Schematron tools.
This Committee Specification is an OASIS deliverable, completed and approved by the TC and fully ready for testing and implementation.
