we have a fundamental problem that XSD datatypes are hard to map properly to
simple java datatypes. Ultimately, you want a set of classes that exactly
model the behavior of XSD types, right down to facets and things, so you
cannot work with them outside the envelope that the schema defines. But
because XML Schema is such a baroque mess of concepts this is really, really

we need definitions for all the unsigned types that from other peoples WSDL
at the very least.
