Have you tried
  <http://www.w3.org/2013/ShEx/FancyShExDemo?schemaURL=Examples/Issue-simple-annotated.shex&dataURL=test/Issue-pass-date.ttl>
? Look for "View as <SPARQL query> <SPARQL remaining triples>".

The former tests validity; the latter tells you which triples were not
covered by the pattern (which is *an* answer to the open/closed shape
discussion as well).
