The year of copyright.
Since the <copyright-statement> element is intended for display, this element’s contents may not be displayed (but will be available for searching). The <copyright-year> element need not be used, if having the year as part of the <copyright-statement> is sufficient. (See <copyright-statement>.)
Historical Note: This element (<copyright-year>) was significantly remodeled for NLM 3.0. The current JATS values are backwards compatible with NLM 3.0 but not with earlier versions. Specifically, in prior versions the <copyright-year> element was allowed outside the <permissions> container element (although this was not best practice).
