Are the choices as large as minOccurs>0? Or the only choice when false is minOccurs=1?

Yes. Any nonNegativeUnbounded greater than zero. If it is supposed to be minOccurs=1 when optional=false then I can change that of course.

optional is only a synonym for minOccurs=0 when optional=true.
When optional is false, this must mean the opposite so minOccurs>0 since nonNegativeUnbounded (not specifying the exact value of minOccurs, we only know it is greater than 0).
