Introduction to DocBook XML Schemas 5.1

The DocBook XML Schemas-5.1 package contains schema files and Schematron rules for verification of XML data files against the DocBook rule set. These are useful for structuring books and software documentation to a standard allowing you to utilize transformations already written for that standard.

[Note]

Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Installation of DocBook XML Schemas 5.1

[Note]

Note

The package source is distributed in zip format and requires unzip (or bsdunzip from libarchive). You should create a directory and change to that directory before unzipping the file to ease the removal of the source files after the package has been installed.

Install DocBook XML Schemas by running the following commands as the root user: 

install -vdm755 /usr/share/xml/docbook/schema/{rng,sch}/5.1         &&
install -m644   schemas/rng/* /usr/share/xml/docbook/schema/rng/5.1 &&
install -m644   schemas/sch/* /usr/share/xml/docbook/schema/sch/5.1 &&
install -m755   tools/db4-entities.pl /usr/bin                      &&
install -vdm755 /usr/share/xml/docbook/stylesheet/docbook5          &&
install -m644   tools/db4-upgrade.xsl \
                /usr/share/xml/docbook/stylesheet/docbook5

Create (or update) and populate the /etc/xml/docbook-5.1 catalog file by running the following commands as the root user: 

if [ ! -e /etc/xml/docbook-5.1 ]; then
  xmlcatalog --noout --create /etc/xml/docbook-5.1
fi &&

xmlcatalog --noout --add "uri" \
  "http://www.oasis-open.org/docbook/xml/5.1/rng/docbook.rng" \

While again as the root user, create the individual catalogs: 

xmlcatalog --noout --create /usr/share/xml/docbook/schema/rng/5.1/catalog.xml &&

xmlcatalog --noout --add "uri" \
  "http://docbook.org/xml/5.1/schemas/rng/docbook.schemas/rng" \
