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.

What do you think of
public class ConstraintValidatorContext {
     addInterpolatedParameter(String name, String value);

public class SyntaxValidator implements ConstraintValidator<Syntax,

         detectedSyntax = ...;

@Syntax(value={JAVA, HTML}, message="{constraint.syntax}")

ValidatorMessage_en.properties
