Now we may be getting somewhere.

What are these practical applications that you think require shape checking?

My canonical application for constraint checking is that I am writing a 
program to consume RDF graphs, and I want to know that some information is 
explicitly present in that RDF graph.  For example, I want to know that each 
graduate student has a university explicitly given and that that university is 
a research university.
