There was a time when I used to write documentation in sgml quite a lot. Usually I processed these input files with docbook2... to generate html, pdf, txt, etc.
Today I wanted to build an old project of mine that I hadn't looked at in about 4-5 years, including its documentation.
When docbook2... ran, however, it generated lots of:

On openSUSE, apparently, the xmlcharent stuff is provided by the package xmlcharent, but the sgml configuration file, /etc/sgml/catalog, is provided by the package sgml-skel.
The xmlcharent package went through some updates recently, and the /usr/share/sgml/CATALOG.xmlcharent file has been replaced by /usr/share/xmlcharent/xmlcharent.sgml. Therefore one needs to update /etc/sgml/catalog manually and change the first line from /usr/share/sgml/CATALOG.xmlcharent to /usr/share/xmlcharent/xmlcharent.sgml.
