I agree that CSS was designed to be fairly simple for authors to use.
I have read about DSSL but seen few examples of a DSSL application so I 
don't know if it is signicicantly harder to write.

At the W3C stylesheets workshop at Versailles in November 95 several 
proponents of DSSSL stated that anything CSS could do, a DSSSL application 
could be made to do.

So, using CSS gives a clear upgrade path if DSSSL turns out to be more useful.
It also means that CSS stylesheets should be readilly convertible to DSSSL on 
the fly by a  a DSSSL-based browsing tool.

Yes, that should work.

I wouldn't go that far. DSSSL could well be useful with HTML too.
