This could be a problem.  The version of Xerces that ships with JDOM b7 is 1.2.0, from 09/2000, so it's unlikely to support
the schema spec of 2001.  It's probably wanting:


where XX is some month, although I don't know which one.

What I would try first is to download the latest version of XercesJ 1 from www.apache.org, and use that xerces.jar instead of
the old one that shipped with JDOM b7.  Then you can use xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance".

I see that you tried using XercesJ 2, which maybe you thought was the latest version of the Xerces jar that shipped with
JDOM, but actually Xerces J 2 is a completely different parser to XercesJ 1, and does not support schema validation yet, I

The latest official Xerces release is 1.4.3.

Good luck.
