[xml/sgml-pkgs] Bug#318817: xsltproc: Trys to access network entity when --nonet is specified

[Karl O. Pinc]

Package: xsltproc
Version: 1.1.12-8
Severity: minor

When I generate any sort of output from docbook I get 
the message:

I/O error : Attempt to load network entity
http://www.oasis-open.org/docbook/xml/4.3/docbookx.dtd

I see that xsltproc is called with '--nonet' so I would not expect to
see this message.  I'm not sure this is the package where the problem
lies....

I can generate txt output just fine, AFIK, but not PDF output.  I'm
filing another bug for the PDF problem in case it's unrelated.

See also: Debian bug #286540
I note that wget can retrieve the url content without a problem.

The first 3 lines of my xml file are:
<?xml version='1.0'?>
    <!DOCTYPE article PUBLIC "-//OASIS//DTD DocBook XML V4.3//EN"
           "http://www.oasis-open.org/docbook/xml/4.3/docbookx.dtd">

There's no problem on a RedHat AS 3 system upgraded to support
docbook 4.3 with rebuilt rpms from Fedora (or maybe AS4):
docbook-style-xsl-1.65.1-2.noarch.rpm
docbook-dtds-1.0-25.noarch.rpm
docbook-utils-0.6.14-4.noarch.rpm
docbook-style-dsssl-1.78-4.noarch.rpm
docbook-utils-pdf-0.6.14-4.noarch.rpm

I also note (FWIW) that:
/usr/share/xml/docbook/schema/dtd/4.3/catalog
says:
  -- public identifiers override system identifiers, if both are supplied   --
OVERRIDE YES

This is different from the RH system.
Or maybe there some other problem in the mapping to local files?
