% PURPOSE
%-------------------------------------------------------------------------------
% This module offers no system functionality. It provides a location for
% modules to store their type and data descriptions. By providing a uniform
% interface, rather than embedding this information into comments, the
% expectation is that it will be more consistent, better maintained and
% easier to read.

% As this module manages types and data, it is unable to initially manage
% its own types and data until the whole module has been parsed. For this
% reason the types and data declarations are contained in a predicated and
% dynamically invoked at the end of the module.
