One approach might be to add some gnome-specific (or gtk+ specific)
extensions to DV's libxslt - there is a standard mechanism to do this,
ad his library supports it, so that you could add functions to get
at font choice, size, line spacing, colours, etc.

An XSLT stylesheet can also ask if a partiular extension exists, and
fall back to defaults if it doesn't, so that the help files would still
work if you had an unmodified xslt processor.
