%% @doc The following types describe an abstract format for status information.
%% Each type has a semantic, organizational meaning in a way similar to an html
%% document. The difference here is that we want our format to use erlang
%% data structures and types and be able to generate human readable output, json,
%% csv and a subset of html, as well as other possible output.
