When running xmllint to validate the docs tree, the dtd will be
source locally before trying to load as external entity. Since
the oasis-open.org entity was moved to redirect to HTTPS this
no longer works as xmllint only supports http. Fix by installing
the DTD locally via the docbook-xml package (as per the postgres
documentation).
Below is the errormessage incurred:
/usr/bin/xmllint --path . --noout --valid postgres.sgml
error : Unknown IO error
postgres.sgml:21: warning: failed to load external entity "http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd"
