I would be interested in getting dynamic constraint functionality into the BV spec. Between what Hibernate Validator offers and what is supported by the dynamic add-on for Apache BVal it shouldn't take us much to agree on an API.

Let me try to be a bit more clear.
Consider this entity:

@Entity
public class Employee
{
    private String _name;

    // ...

    @Size(min = 1, max = 50)
    public String getName()
    {
        return _name;
    }

    // ...
}

If some client of mine asked me to change the name of the employees to accept 70 characters because 50 is not enough anymore I have to change my application for all clients. But if the bean validation specification allowed me to configure the constraints dinamically I could do this configuration on a cliente basis. All I had to do was to change the database structure for the specific column, register this fact in some table of mine and in the application startup my application would check for changes and configure the corresponding bean constraint. With static constraints (as it is today) we don't have this flexibility.

Hi
We don't have a defined roadmap for the future of Bean Validation. But that would be a nice addition in my opinion.

What's your use case for it?
