The DocBook Technical Committee [DocBookTC] maintains the DocBook schema. Starting with V5.0, DocBook is normatively available as a [Relax NG] Schema with some additional Schematron assertions. DocBook Version 5.1 [DocBook-5.1]was released as a Committee Specification on 11 November 2015.
The most recent Schematron tools do not work with [DocBook-5.1]. This DocBook 5.1.1 specification is updated with the new Schematron rules so users can continue using DocBook 5.1 if they need to use newer Schematron tools. No changes were made to DocBook elements, attributes, or content models. So any document that conformed to DocBook 5.1 will still conform to DocBook 5.1.1.
This document describes only the changes that were made to DocBook Version 5.1 to bring it into conformance with the new Schematron version. For other information about DocBook Version 5.1 and how it differs from previous versions, see the OASIS Standards document for [DocBook-5.1].
Certain title elements in the Schematron rules in [DocBook-5.1] had the wrong namespace prefix. This update fixes those elements to use the correct namespace.
In the RelaxNG files such as docbook.rnc, there are 119 instances of a Schematron rule to ensure that a DocBook element used as a root element in a document has a version attribute. In [DocBook-5.1] those rules used the wrong namespace prefix rng: for the Schematron title element:
rng:title [ "Root must have version" ]
In all 119 instances, these were changed in this updated version to the correct s: namespace prefix :
s:title [ "Root must have version" ]
Since the <s:title> in Schematron assertions is not necessary for validating DocBook document instances, this change will not require any changes to the conformance rules for existing DocBook documents. So the Conformance section of the DocBook 5.1 [DocBook-5.1] standard is unchanged.

[OASIS requests that any OASIS Party or any other party that believes it has patent claims that would necessarily be infringed by implementations of this OASIS Standards Final Deliverable, to notify OASIS TC Administrator and provide an indication of its willingness to grant patent licenses to such patent claims in a manner consistent with the IPR Mode of the OASIS Technical Committee that produced this deliverable.]
[OASIS invites any party to contact the OASIS TC Administrator if it is aware of a claim of ownership of any patent claims that would necessarily be infringed by implementations of this OASIS Standards Final Deliverable by a patent holder that is not willing to provide a license to such patent claims in a manner consistent with the IPR Mode of the OASIS Technical Committee that produced this OASIS Standards Final Deliverable. OASIS may include such claims on its website, but disclaims any obligation to do so.]
[OASIS takes no position regarding the validity or scope of any intellectual property or other rights that might be claimed to pertain to the implementation or use of the technology described in this OASIS Standards Final Deliverable or the extent to which any license under such rights might or might not be available; neither does it represent that it has made any effort to identify any such rights. Information on OASIS' procedures with respect to rights in any document or deliverable produced by an OASIS Technical Committee can be found on the OASIS website. Copies of claims of rights made available for publication and any assurances of licenses to be made available, or the result of an attempt made to obtain a general license or permission for the use of such proprietary rights by implementers or users of this OASIS Standards Final Deliverable, can be obtained from the OASIS TC Administrator. OASIS makes no representation that any information or list of intellectual property rights will at any time be complete, or that any claims in such list are, in fact, Essential Claims.]
