Re: Constraints on classes

I believe that approved requirement 2.12.2
http://www.w3.org/2014/data-shapes/wiki/Requirements#Selection_by_type
covers these situations.   User story S2 is based on selection by type.

Both SPIN and Stardog ICV can do this, as can both of the SPARQL-based
proposals.  I don't believe that Shape Expressions can do this without having
bare negation.  As far as I can tell, Resource Shape 2.0 can't do this,
although I  remain confused as to how Resource Shape 2.0 works.
