 /**
 23   
  * The canonical implementation of {@link org.apache.tapestry.engine.ServiceEncoder}, it encodes
 24   
  * page name and a service name. The page name becomes the servlet path, prefixed with "/" and
 25   
  * suffixed with a dot and a particular extension. In this way, "/app?service=page&page=Home"
 26   
  * becomes simply "Home.html". This is most suitable for the "page" and "external" services.
