make.year.ranges — Collate copyright years into ranges?


<xsl:param name="make.year.ranges" select="0"></xsl:param>


If non-zero, multiple copyright year 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.
