Thanks for the review. My goal was to be precise. If we are all in
agreement, then we can work on improving the readability.

I think we should do some editorial work to explain the shapes graph,
the data graph, and how typing works, probably nearer where we discuss
the relation to RDFS. Then go through the whole spec and much sure we
are consistent.

A couple of issues occur to me, e.g, we were giving rdfs:Resource
special treatment in the definition of sh:class (all classes are
subclasses of rdfs:Resource). Also, we do not require the presences of
an explicit sh:Shape type triple in some cases, i.e. we are in effect
inferring the type from the context.
