Yeah, suggesting fixes is really a nice-to-have, and this feature has 
not been used much so far in our experience. Fortunately we are in RDF 
where anybody can add extra triples to an existing object, e.g. add 
"annotations" to a constructed spin:ConstraintViolation object. That's 
one reason why we went with constraint definitions based on CONSTRUCT.
