The year of a copyright of the article
Since Copyright Statement is intended for display, this element’s contents may not be displayed (but will be available for searching). The Copyright Year need not be used, if having the year as part of the Copyright Statement (see <copyright-statement>) is sufficient.
Best practice is to use the <copyright-statement> and <copyright-year> elements only within the container element <permissions>. The <copyright-statement> and <copyright-year> elements are allowed outside the permissions wrapper only for reasons of backwards compatibility.
