The idea of specifying logic in a schema is certainly compelling. On the
other hand we use schemas not for generating code for internal use but to
allow other organizations to work with our data without having to write all
the object model and marshalling code themselves, *if they are not also
using Java*, that is, in which case they can use the more powerful tools we
provide. For any extensions to be of any use, they must therefore by widely
available and standardized. Of course someone always has to make a

Another issue is that you probably won't be able to specify all behavior you
may want to attach to your data with such extensions, unless the extension
would in fact contain a full-blow programming language independent
programming language. For the time being I would rather specify all behavior
in plain English than having a half-half solution.

One question (before I actually try it out...): does your framework
(un)marshal large files that don't fit into memory?

Also, is the licensing term really open-source compatible? Not that I object
to anyone getting paid for their work, but we must distribute our data
publicly and integrating features (even if optional) that require licensing
in certain cases is problematic at best.
