Hi!

Perhaps I can make things a little clearer :)
As Greg says, I install the DTD and stylesheets out of the way of the
system versions. I setup my own catalog and use that so the system
catalog is not used, in the long run I will make it possible to not
install these things with a configure-flag so that distributions that
set things up correctly don't have to have two copies of these (about
1.5 MB hard disk space).

In the even longer perspective our stylesheets will work with "current"
of Norms stylesheets and we can make that a dependency and have the
distributions make this correctly.

As for the DTD it has to be shipped to since it's needed to convert
since lots of the entities used in Docbook is defined in the DTD. On the
other hand lots of system has a working DTD catalog but not the
stylesheets. The Stylesheets are tougher too since we need exactly 1.48
and most systems either has older or newer versions installed.
