Thanks for pointing that out. We will correct this right away.
This is our first time writing RDF schema, so it might have some
errors.

Does anybody know RDF validator which actually uses RDF schema
when validating document?

Yes, this is probably way to go. I was thinking about this approach,
but I did not know how express in RDF schema something of notion of
"abstract" class. I would like somehow to specify that this base class
not suposed to be used in the documents itself - only its subclasses.
Maybe making it "blank node" would do the trick?

I will take a look at it and think if that belongs to mod_enclosures
or should be defined outside.
