I think I have a lead but not a solution. I hadn't noticed that the log
file is logging a backtrace despite returning valid XML. The backtrace is:
2013-05-07 15:09:07,730 WARN [geoserver.wfs] - Could not build xml schema

In SQL Server we do have the ID field defined as type 'uniqueidentifier'.
Is there a way to add support for type java.util.UUID, or do I need to
rework my database tables?
Thank you,
