Re: Detecting stylesheets and DTDs

[Alexander Kirillov <kirillov math sunysb edu>]

Once again: we are just asking for disaster - on greater majority of
distro's,  DTD and stylesheet are not properly registered in xml
catalog. Yes, of course, this is the packagers' fault - so what? Whoever
is to blame, the users  will be the victims.  You can't expect all users
to update their catalogs themselves. For example, I have relatively
recent distro (Mdk 8.1), I installed libxml2, libxslt, stylesheets, but
on my machine, I get this:

[shurik localhost shurik]$ xmlcatalog /etc/xml/catalog
http://docbook.sourceforge.net/release/xsl/current/html/chunk.xsl
No entry for SYSTEM
http://docbook.sourceforge.net/release/xsl/current/html/chunk.xsl

OK, I know how to fix it. But average user does not. And we can't hope
that an average user will go to DV's web page to read instructions, nor
do I think he should. 

My only suggestion is that we give the user link to updated  DTD and
stylesheets packages which correclty register in XML catalog, for all
major distros. If there are no such packages, we - or GNOME packaging
project - must create them before releasing GNOME 2.0. GNOME is meant to
be installed by ordinary users, not hackers.
