% Het onderstaande is nodig om \type af te handelen in

% Het actief maken en toekennen moet zeer vroeg gebeuren,
% in ieder geval voordat cont-00a wordt geladen. Zoniet,
% dan gaat het mis op commando's als \processaction. De
% mathematische mode en vergelijken van waarden met \if
% gaat echter wel goed.

% Omdat in een acrobat geen < en > in een label mogen
