Looking for a .fodt validator

[Hendrik Boom <hendrik@topoi.pooq.com>]

I found an .odf validator online at http://opendocumentfellowship.com/
validator (upload a file and it tells you if it likes it), but it doesn't 
handle fodt.  It complains it hasn't been compressed and packaged as 
a .zip file.  Now surely it's *less* work to check .fodt, because you 
don'thave to do all that pesky unzipping, but ...

Anyone know a validator that checks .fodt files?  I'm generating my 
own .fodt and OpenOffice is crashing on it, so presumably there's 
something wrong.
