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

    This class may be used as a base class for tag instances that support specific Converter subclasses.

    Subclasses of this class must implement the createConverter() method, which creates and returns a Converter instance. Any configuration properties that specify behavior of this Converter must have been set by the createConverter() 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 Converter creation.
