# instantiations of this grammar may replace leaf strings
# with more elaborated types; e.g. title (text) replaced with
# title_main, title_intro, title_part; type replaced with
# enum.
#
# some renaming at leaf nodes is permissible
#
# obligations can change both from optional to mandatory,
# and from mandatory to optional; optional elements may
# be omitted; freely positioned alternatives may be replaced
# with strict ordering
