-;;;; Name: ml.lisp
-;;;; Purpose: Markup Language Class
-;;;; Programmer: Kevin M. Rosenberg
-;;;; Date Started: Sep 2002
-;;;;
-;;;; This class defines functions for classes to allow display
-;;;; in Text, HTML, and XML formats. This includes hyperlinking
-;;;; capability and sub-objects. This is a re-write of ml-class.lisp
-;;; which used fairly difficult to port metaclass features.

-;;; Design:
-;;; ml-class hold all formatting information for an object
-;;;
-;;; When a class is definited with the def-ml-class macro, a formatting
-;;; object named _<name>-ml-fmt_ is created. Then, when a ml-class object
-;;; is to be printed, the formatting object is referenced.
