Jody, I'm moving this discussion to the geotools users list as per your request.

I tried to look at the gt-xml, gt-app-schema, gt-wfs test cases, but, well, maybe I'm not clever enough to find out which ones are the ones you're referring to, that would simply parse an XML document which is described by an XML Schema, and create a Data Store from it. > > The content you get back should be features, the simple attribute > represented as java types, and your complex types represented as > java.util.Map (since there is no binding to a concrete Java > class).

I already did that for myself, isolated a smaller part of the whole schema, so that initally the scope is smaller and can be managed easier. > > I will remind you that you a are on the geotools-devel list here, if > this is work you are doing internally for your company you should move > discussion to the geotools user list, thank you, did that, sorry for posting on the wrong list > or if you are up against a deadline I encourage you to explore options > for commercial support > (http://docs.geotools.org/latest/userguide/welcome/support.html). > Several organisations are listed there, including my employer. I tried, and I had to face the fact that I can't afford this at the moment. the project I'm doing is a non-profit open source project done in my free time and from my personal resources.
