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).

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.
