I was actually just thinking about that Jeremy. The way I generate the
files right now is by reproducing all the classes from the XSD file
and simply marshalling them out. In any case, all the info and
structure is there, it should not be that hard to get Castor to
generate the information on the fly.
And, for the actual JDO instance, that is now (I believe), already
completly buildable through code as is, so it would be a matter of
supplying the information for that somewhere.
