<para>If non-zero, multiple copyright <tag>year</tag> elements will be
collated into ranges.
This works only if each year number is put into a separate
year element.  The copyright element permits multiple
year elements. If a year element contains a dash or
a comma, then that year element will not be merged into
any range.
