    Use an URN for DTD ID · 9c46ef4a

    XML tools interpret “fonts.dtd” as a relative path.
    
    Unfortunately, that can not work now that the configuration is spread over
    multiple system-dependant directories, without a common relative path to this
    file. And, an absolute path can not be defined in a system-independant way.
    System independance is a requirement to share config files between systems.
    
    Therefore, replace the broken relative path by a formal URN, that will work the
    same way on all systems, without network access.
    
    This makes the DTD registerable with commands like:
    $ xmlcatalog --noout --add system \
                               "urn:fontconfig:fonts.dtd" \
                               "file:///usr/share/xml/fontconfig/fonts.dtd" \
                               /etc/xml/catalog
    
    That enables easy config file checking:
    $ xmllint --loaddtd ${config_file} >/dev/null
