Now I understand some design decisions in tools much better. Additional problem is that with existing SimpleValue I can't distinguish between CustomType and enumeration, an I have to because they generate different annotations (@Type vs @Enumeration + enum definition). Are you aware of any other types that are parametrized and require special handling? When do you plan to introduce columnToHibernateTypeProperties(...)?
