Overview

SAX handler counting elements, mirroring the Nokogiri adapter's StreamingHandler shape (Leptris SAX delivers attrs as [name, value] pairs, same as Nokogiri::XML::SAX). Plain duck-typed class -- Leptris::XML::SAX::Parser needs no base class, and subclassing it would trigger the FFI library load at file-load time.
