DocBook v5.1 is now an official OASIS Standard!

OASIS is pleased to announce that DocBook Version 5.1. has been approved by the membership as an OASIS Standard [1].

The call to vote was made on 09 November 2016 [2] and the ballot closed on 22 November 2016. A minimum of 42 affirmative votes was needed in order to win approval. The finally vote tally was 63 affirmative votes with 4 abstentions. 

Our congratulations to the members of the TC and to the community of implementers, developers and users who have brought the work successfully to this milestone

DocBook is a general purpose [XML] schema particularly well suited to books and papers about computer hardware and software (though it is by no means limited to these applications).

The Version 5.1 release introduces assemblies for topic-oriented authoring. It also addresses a selection of bugs and feature requests.

The Technical Committee provides the DocBook 5.1 schema in other schema languages, including W3C XML Schema and an XML DTD, but the RELAX NG Schema is the normative schema.
