need a working sgml catalog file

[nlany@uibe.edu.cn]

I downloaded website DTD, which comes with a xml catalog file.
Since I want to use psgml in Emacs, I have to use sgml version of that 
catalog file.
I wrote one as in the attachment, but I got some error message when 
emacs parsing the DTD, like this:

/usr/local/share/sgml/docbook/website-2.5.0/website.cat line 12 col 21 
entity para.char.mix
/usr/local/share/sgml/docbook/website-2.5.0/schema/dtd/website.dtd line 
626 col 38 entity WEBPAGE
/home/nlany/tex/webtest.xml line 3 col 80
Delimiter GRPC ()) expected; at: :input|html:

I'd like to investigate the problem, but if someone already have a 
working sgml catalog psgml, please send me a copy, or better contribute 
it to the release maintainer.

help!
