[xml] libxml2: xmlcatalog --sgml --noout --add <catalog> generates odd behavior

[Mark Johnson <mjohnson redhat com>]

Hi All,

I don't have the latest versions of libxml2/libxslt because they 
won't install on my FC2 machine. Here are the versions:

libxml2-2.6.8-1
libxslt-1.1.5-1

I noticed the odd behavior while packaging simplified docbook. I 
simply wanted to register the central/package catalog 
/etc/sgml/docbook-simple.cat in the root catalog /etc/sgml/catalog.

I used the command:

/usr/bin/xmlcatalog --sgml --noout --add \ 
"/etc/sgml/docbook-simple.cat"

The odd behavior is that xmlcatalog actually modified the 
docbook-simple.cat file, by removing any comments and also removing the
'OVERRIDE YES'
SGML catalog directive.

(Yes, I know I can also use /usr/bin/install-catalog, but that does 
something quite funky as well: it adds a
'CATALOG "/etc/sgml/catalog"' line to the end of docbook-simple.cat.)

Attached is the docbook-simple.cat file.

I can work around this, but thought I should nonetheless report it.

Thanks,
Mark
