/**
 * 
 *   Basic interface to be implemented by all processors provided by processor dialects (implementations of
 *   {@link IProcessorDialect}).
 * 
 * 
 *   Note this is a base interface without much meaning of its own. Instead, processors
 *   should implement one or several of the following sub-interfaces:
 * 
 * 
 *   {@link org.thymeleaf.processor.element.IElementTagProcessor} execute on open/standalone
 *       tag events only (no processors can be applied to close tags), and have no (direct) access to the element
 *       body.
 *   {@link org.thymeleaf.processor.element.IElementModelProcessor} execute on complete
 *       elements, including their bodies, in the form of {@link org.thymeleaf.model.IModel} objects.
 *   {@link org.thymeleaf.processor.templateboundaries.ITemplateBoundariesProcessor}
 *       execute on template start ({@link org.thymeleaf.model.ITemplateStart}) and/or template end
 *       ({@link org.thymeleaf.model.ITemplateEnd}) events.
 *   {@link org.thymeleaf.processor.text.ITextProcessor} execute on {@link org.thymeleaf.model.IText} events.
 *   {@link org.thymeleaf.processor.comment.ICommentProcessor} execute on {@link org.thymeleaf.model.IComment}
 *       events.
 *   {@link org.thymeleaf.processor.cdatasection.ICDATASectionProcessor} execute on
 *       {@link org.thymeleaf.model.ICDATASection} events.
 *   {@link org.thymeleaf.processor.doctype.IDocTypeProcessor} execute on {@link org.thymeleaf.model.IDocType}
 *       events.
 *   {@link org.thymeleaf.processor.xmldeclaration.IXMLDeclarationProcessor} execute on
 *       {@link org.thymeleaf.model.IXMLDeclaration} events.
 *   {@link org.thymeleaf.processor.processinginstruction.IProcessingInstructionProcessor} execute on
 *       {@link org.thymeleaf.model.IProcessingInstruction} events.
 * 
 * 
 *   Note a class with this name existed since 2.0.0, but it was completely reimplemented
 *   in Thymeleaf 3.0
