Yeah, I already have one (using owl restrictions), but not quite done
yet.  I'll probably just throw it online separately if it's larger than
the restrictions-in-comments versions, otherwise I guess we can fight
about it :)

I was hoping there would be tools that would mean such an LV2 ontology
would make for a "free" plugin validator, but owl tools have... some
issues.  Many of them reject an ontology if it has triples the validator
doesn't understand (ie the maintainer etc info in lv2.ttl).

Eeeeeevil * 9999.  So anti-RDF :/  Logic people write good ontologies
and shitty software.  I guess this isn't exactly a world shattering
surprise :)

Anyway, even if an LV2 specific validator will be written, it's
definitely better to do it based on restrictions in RDF and not
assumptions in code.

I might try building some of this into SLV2, but it's not a huge
priority ATM.  If your plugins don't work, they're not valid. :)
