public class TagTransformer
extends AbstractXMLProducer
implements Transformer, Serviceable, Configurable, Disposable, Recyclable

Transformer which implements the taglib functionalty.

Transformer processes incoming SAX events and for each element it tries to find Tag component with matching namespace and tag name.
