    # 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 (applied to the output of the group
    # as a whole) and formatting attributes (transmitted to the enclosed
    # elements).
    #
    # 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.
