For the PG community I would like to raise the question: Do we need
DocBook in the distro of any operating system? In the past we developed
some stylesheets to adopt DocBook to our needs. They are part of PG's
distro and refer to the standard with statements like <xsl:import
href="http://docbook.sourceforge.net/release/xsl/current/xxxx/docbook.xsl"/>. With the migration to db5.x the links change to <xsl:import href="http://cdn.docbook.org/release/xsl/1.79.2/xxxx/docbook.xsl"/>. Hence we don't need any additional local stylesheet outside of our own distro. Concerning DTD/schema/relax-ng: In db5.2 there is no DTD nor a XML-schema, for validation we need only the Relax-NG file 'docbook.rng'. This file is available at https://docs.oasis-open.org/docbook/docbook/v5.2/os/rng/docbook.rng (during the conversion-process I used a local copy).
I assume we don't need any operating system distro of DocBook. Please
correct me, if I'm wrong.
Note that we run xsltproc with the --nonet option. So stylesheet and
schema need to be available as local files. Downloading these
on-the-fly during the build process has been found to be unreliable, and
it's also not sound software supply chain hygiene.
