Hmm...  Is the machine you're working from online?  We've had problems 
before (which I thought I had fixed) where Java was making a call to an 
external site during schema validation.  If that's not the case I'm not 
sure what the problem would be.  The prefix is definitely declared on 
line 4 of the file.

Ooopss, another thing I have to document is the default object provider. 
 Let me get this documentation out there and I'll point you to it. 
I'll also fix the config files so that they use.

By the way, thanks for all the feedback.  It's helping me get this stuff 
whipped into shape.  Certainly feel free to give me any comments you 
have on the documentation out on the wiki.
