Frans:

I'm curious which SGML features KDE is using, and what processing tools
you're using for your DocBook.  We dropped SGML support in Gnome about a
year ago, so this is potentially a serious interchange issue, especially
if we ever standardize on a single help system.

Norm:

The officially supported version of DocBook for Gnome is still 4.1.2,
although most 4.2 and 4.3 features will work.  I'm trying to push our
documents to a newer version, mostly because we want to use xrefstyle. 

Assuming 5.0 is similar to "DocBook NG", Gnome could probably support it
within one release cycle after the 5.0 release.  I strongly favor the
RELAX NG approach, and I'll be pushing all of our documents towards this
just as soon as there's an official release.

I think I can speak for Gnome when I say, "Go Norm!"
