just to add little infos.

with the .xsd that I provide JAXB and Xmlbeans works.  Maybe it's not
suppose to work with a xml that didn't respect the sequence order (I don't
know enough Xml Schemas), but I'm able to unmarshal and marshal.

so for me it's enough for now.. I think.. maybe I'll found a problem later.

thanks
