One problem.
The content of my catalog file is:
-- AUTOMATICALLY GENERATED, DO NOT EDIT --
CATALOG "/usr/share/sgml/entities/iso-entities-8879.1986/iso-entities.cat"
CATALOG "/usr/share/sgml/dtd/docbook/3.1/docbook.cat"
CATALOG "/usr/share/sgml/stylesheets/docbook/catalog"
CATALOG "/usr/share/sgml/dtd/jade/dsssl.cat"
CATALOG "/usr/share/sgml/dtd/sgmltools/catalog"
CATALOG "/usr/share/sgml/stylesheets/sgmltools/sgmltools.cat"
CATALOG /etc/sgml/sgml-docbook-3.0.cat
CATALOG /etc/sgml/sgml-docbook-3.1.cat
CATALOG /etc/sgml/sgml-docbook-4.0.cat
CATALOG /etc/sgml/sgml-docbook-4.1.cat
CATALOG /etc/sgml/xml-docbook-4.1.cat
in /etc/sgml/catalog, and as you see this is list of catalog files.
config_xml doesn't understand this. Is it sgml specific?
