[hibernate-dev] [Bean Validation] Adding interpolation facilities

[Hardy Ferentschik]

Wouldn't this also mean that you have to change the MessageResolver  
interface from

  MessageInterpolator.interpolate(String message, ConstraintDescriptor<?>  
constraintDescriptor, Object value)

to

  MessageInterpolator.interpolate(String message, ConstraintDescriptor<?>  
constraintDescriptor, Object value, Map<String, String>  
interpolatedParameters)

I can see the potential use case, but I am not sure whether it is worth  
the added complexity in the API.
