% \begin{macro}{\DeclareSpecialMarkup}
%   Command to declare special markup commands, that behave different in- and
%   outside |Description| environment. Parameters are:
%   \begin{declaration}
%     \item[\arg{command}:] The the markup command, that should be defined.
%     \item[\arg{outside definition}:] Definition of the markup command
%       outside |Description| environment.
%     \item[\arg{inside definition}:] Definition of the markup command inside
%       |Description| environment.
%     \item{\oarg{inside end definition}:] Definition of the \cs{end} command,
%       if inside |Description| an markup environment instead of an markup
%       command would be used.
%   \end{declaration}
%   At the end color \meta{command name} will be black and \cs{\meta{command
%   name}}, \cs{text\meta{command name}, \cs{Desc\meta{command name}}, and
%   optionally \cs{endDesc\meta{command name} will be defined, with
%   \cs{\meta{command name}} is \meta{command}.
