Here's a simple recipe, starting with a clean Etch chroot:

# apt-get install docbook-xml
# sed -i s/etch/lenny/ /etc/apt/sources.list
# apt-get update
# apt-get -d install perl-modules docbook-xml
# cd /var/cache/apt/archives
# dpkg --unpack perl-modules_5.10.0-*.deb docbook-xml_4.5-5*.deb

I still think the only options to fix this for sure are to change
the docbook-xml postinst or to make the package pre-depend on a fixed

Fortunately docbook-xml does seem to be the only package affected after all.

I've gone through my earlier list of packages using dh_installxmlcatalogs,
and there are only six packages with a newer version in Lenny than in
Etch. Out of these, all the other five can be upgraded succesfully with
the above recipe.

I think (but haven't systematically verified) that the other five
succeed because they re-register the same catalog information in the
postinst, so it doesn't matter that 'prerm upgrade' failed to remove
the old information.

(The update-xmlcatalog script only bails out with an error if asked to
 add catalog information with an existing key but different contents. If
 the key and the contents match existing data, it will just exit

For reference, the packages I've gone through are
