Re: TransReq: CR for SHACL, from RDF Data Shapes WG

Addendum.   As requested, we've added a normative appendix "SHACL Shapes 
to Validate Shapes Graphs", and identified the feature that would need 
to change to support Generalized RDF.  These are both "At Risk" to allow 
some flexibility during CR.  WG decisions at 
https://www.w3.org/2017/04/05-shapes-minutes.html#ResolutionSummary .

Please consider the request re-submitted.
