+1  the SPARQL queries in

https://w3c.github.io/data-shapes/shacl/#sparql-template-defs

can easily be used for different purposes without any deep understanding 
of templates. The only thing people need to understand is

- in those SPARQL queries, certain variables such as ?minCount are the 
input from the constraints
- the variable ?this represents the focus node. I have set those 
pre-bound variables to a blue font to clarify their special role.
- the result variables such as ?root and ?path represent the constructed 
errors
