class CSL::Style::Group

The Group rendering element must contain one or more rendering element (with the exception of {Layout}). Group nodes may carry the delimiter attribute to separate their child elements, as well as affixes and display attributes and text formatting (applied to the output of the group as a whole).

Groups implicitly act as a conditionals: a Group and its child elements are suppressed if a) at least one rendering element in the Group calls a variable (either directly or via a macro), and b) all variables that are called are empty.
