% henrikt-ma: Introducing semantic macro for 7 definitions spread out over two chapters
% that for unclear reasons use their own style, including numbering.  Sorting out if numbered
% definitions should be used more or not at all is part of issue #2570.
%
% Definitions are numbered, but are not suitable for use with \autoref, as \autoref is not aware
% of our custom definitions.  (They say there are better alternatives to \autoref, more suited
% for this kind of customization...)  To avoid accidental use of \autoref, a definition should
% also avoid use of \doublelabel, and instead use \definitionlabel.  Instead of \autoref, the definition
% should be referenced using \definitionref
%
% If we'd like to have definitions spanning over several paragraphs, we should use an environment
% instead of a command, but then we also need to find a way to visualize where the definition ends;
% alternatives that come to mind include boxes, indentation, a right-flushed black square, but the
% big challenge would be to find something that also works well with LaTeXML.
