Hi Mike,
if you read the whole discussion and especially the related issue(*), 
you'll see that by specifying minOccurs=0 for null non-primitives will 
cause Axis2 to generate a WSDL from which .NET tools will have problems 
to generate clients. These are .NET bugs, but if they can be avoided 
it's better, otherwise .NET interoperability is severely affected.

IMHO the preferred way to solve this would have been to have a flag 
(false by default) to use a ".NET friendly" generation algorithm, but 
Amila preferred not to go this way.
