+% Explicit grouping of readings can be achieved by means of the
+% \cs{rdgGrp} command. It takes as mandatory argument the commands
+% used for inserting lemma texts, readings and notes that are
+% described \vpagerefrange{ref:lemmata}{ref:notes-e}, viz.\ \cs{lem},
+% \cs{rdg} and \cs{note}. \cs{rdgGrp} accepts one further optional
+% argument:---\\
+% \DescribeOption{type} |type|$=$\meta{value}\\
+% This named argument is used in the \texttt{TEI xml} output to
+% define an attribute common to all elements representing the
+% variation.
+%
+% Here follows how the technique of explicit grouping would apply to
+% the same passage as above:---
