<@U02SEA99VJB> Hi! I am now using this library in the second project and here we have the requirement to attach metadata to constraint violations. E.g. I validate a list of items that can be in conflict with each other (something like a unique check on an attribute of the list items) and I need to have the conflicting items as metadata for the constraint violation.

The premium solution would be to supply the type of the Constraint Violation as a sealed class to akkurate, so that I can have a "normal" constraint violation with a path and a message, but also specialized types for "This thing here conflicts with this other thing".

Something like this would be the minimum vialable solution: <https://github.com/nesk/akkurate/pull/63>

Any thoughts on that?

We decided to top abusing the library for our very specific use case and switched to fully custom code. We'll keep using Akkurate for form validation and implement our business rules custom.
