If I understand your question, I think what you are asking is out of the current ShEx scope but it can be handled by other tools or it could be added to ShEx processors also. I mean, ShEx just checks the shape of an RDF graph...that graph can be the original graph or it can be the result of applying a reasoner to the original graph, in which case, it would check the original graph plus the inferred triples. An implementation of ShEx could do RDF Schema or OWL inference before applying ShEx so it could check the shape of the inferred graph instead of the original one. At this moment, I didn't incorporate it in Shexcala but it would not be difficult to add a flag to do it.
