Peter, I mean that there is no need to require that sh:valueShape is acyclic. This is form of recursion is useful (based on OSLC use cases) and has a well-founded semantics which I spelled out recently. However, this means that you cannot translate the shape into a single SPARQL query, but that is not a requirement. -- Arthur
