RSS 0.92 was developed by Dave Winer, who is of the
"here's what a sample document looks like" school
of formal specifications :-)
Regarding the RDF schema for RSS 1.0, as far as I know --
please correct me if I'm wrong -- an RDF schema doesn't actually
imply any notion of "validity"; it just makes statements like
"resources of class X may have properties of type Y with a domain
of type Z". (And since any such statement is true already,
regardless of whether or not it is asserted by an RDF schema,
I suspect that RDFS is meant to be informative rather than
prescriptive.)
Leigh Dodds wrote a Schematron schema for RSS 1.0 though:
