Prof. Anne Brugemann-Klein strongly believes that this restriction 
is an extremely bad idea.  I would strongly recommend full support of 
non-deterministic content models.  Otherwise, DTD transformation will become 
impossible, since translated DTD's cannot always be captured by deterministic 
content models.
