JSR303, or probably more specifically Errai's use of GWT's Bean Validation, looks for a validator implementation
for any class that reference a JSR303 annotation. Classes annotated with either @Valid or @Constraint
have a validator class generated. However all of DMN's connectors extend classes that use @Valid but do not
themselves use JSR303 annotations and hence do not have validators generated. This causes problems when Errai
attempts to validate the whole graph. This annotation is therefore used to fool Errai into generating a
validator that does nothing.
