I've noticed that when you specify version 2.1 in
hibernatedoclet, some things don't work as espected.
For example in:
the inverse attribute doesn't appear in the generated
mapping. I've tryed to map a class using both versions
(2.0 and 2.1) and the resulting mappings differs a lot,
the 2.0 generated mapping weigths 11K and the 2.1
version 7K. It seems that more atts are lost in the 2.1
