    extends TagSupport

    ValidatorELTag is a base class for all JSP custom actions that create and register a Validator instance on the EditableValueHolder associated with our most immediate surrounding instance of a tag whose implementation class is a subclass of UIComponentTag. To avoid creating duplicate instances when a page is redisplayed, creation and registration of a Validator occurs only if the corresponding UIComponent was created (by the owning UIComponentTagBase) during the execution of the current page.

    This class must be used as a base class for tag instances that support specific Validator subclasses.

    Subclasses of this class must implement the createValidator() method, which creates and returns a Validator instance. Any configuration properties that specify the limits to be enforced by this Validator must have been set by the createValidator() method. Generally, this occurs by copying corresponding attribute values on the tag instance.

    This tag creates no output to the page currently being created. It is used solely for the side effect of Validator creation.
