The reader is somehow a wrapper around a parser, and a parser can't be "cloned". But in your case I really don't see why you would need to roll back in parsing...that's not needed just check the value. Though I really don't see how you're gonna be able to desambiguate between options for example xsd:float and xsd:double ... That schemas makes no sense to me...
