%D Instead of texdefinitions without arguments, we could have used setups but in my
%D editor the commands stand out better and it also saves an additional component
%D in the name (e.g. common:) because commands and setups have a different namespace.
%D
%D Sometimes we have verbose injections in an entry and these can be language
%D dependent, so we use labels.

%D The variables control the shared code for which we use a tex definition with
%D one argument, specifying the field name.
