The issue is probably that "validation" can mean different things. For simply validating that the RDF grammar is used correctly (xml validation), there is a DTD fragment [1] although this seems to be incomplete [2]. There is also an XSD schema [3], which claims to be complete for all but the RDF abbreviated syntax. Validating the RDF schema itself is a different story altogether, and really shouldn't be the job of DTD or XSD. I notice that two RDF tools (VRP and GINF) claim support for RDF Schema validation. I couldn't characterize how *difficult* this was to implement, but would just point out this is a different thing than XML validation.
