How to easily validate an OpenDocument file (or: where is "oasisfilecheck"?)

[Friedrich W. H. Kossebau]

Hi,

I would like to validate the odg files I create with my CDRv4 import filter. 
Searching for a validator I found
	http://community.kde.org/Calligra/KOffice_and_ODF#Validation
which references "oasisfilecheck" and "oasislint". But the link given is out-
dated (http://www.koffice.org/developer/fileformat/validate.php). And I also 
did not see them in the repo.

That page also points to 
	http://opendocumentfellowship.com/validator
but which seems not to exist for me?

http://wiki.oasis-open.org/office/How_to_Validate_an_ODF_document also only 
links to the old koffice.org page.

So, where is "oasisfilecheck"? Anyone could help me here?

Cheers
Friedrich
