@JSFValidator(name="f:validateDoubleRange",
              bodyContent="empty",
              tagClass="org.apache.myfaces.taglib.core.ValidateDoubleRangeTag")
@JSFJspProperty(name="binding",
                returnType="javax.faces.validator.DoubleRangeValidator",
                longDesc="A ValueExpression that evaluates to a DoubleRangeValidator.")
public class DoubleRangeValidator
extends Object
implements Validator, StateHolder

Creates a validator and associateds it with the nearest parent UIComponent. When invoked, the validator ensures that values are valid doubles that lie within the minimum and maximum values specified. Commonly associated with a h:inputText entity. Unless otherwise specified, all attributes accept static values or EL expressions. see Javadoc of JSF Specification
