Very interesting....

Does your ongoing work also include support for factory methods in addition to constructors? (Not trying to press too hard, just trying to figure out whether this work would be usable; it sounds like it is).

FWIW -- What I've been playing with this morning was support for a factory method without arguments (figuring that argument handling seemed much harder...).

a) added "factory-method" to the mapping.xsd as an optional string attribute of a class.

b) I had started mucking UnmarshallHandler startElement() method adding some clauses near calls to newInstance that would attempt to invoke the provided factory-method if it was specified.

If your work includes this type of functionality, I'll abandon my work and wait. If you would be interested in my work as a contribution (when its finished, which won't be for a little while), I'll continue.

I had figured the same from my preliminary looking into the code. That would certainly be sufficient for my case.
