It's another philosophical question whether oneOrMore components of 
empty models is equal to oneOrMore elements.

I was thinking of this from the point of view of ODD, rather than target 
schema languages. Should ODD support non-deterministic content models 
(natively, rather than through explicit RelaxNG)? If not, then we can 
delete these models prior to output without worrying about the target 
schema language.
