In case of a special issue, the issue title should be added to the issue information of each article by using the <issue-title>-element after the issue number. An example:
Special issue title
<volume content-type="number">9</volume> <volume content-type="year">2018</volume> <issue>2</issue> <issue-title>Special Issue: Reorienting Ancient Judaism: Syrian, Mesopotamian, and Persian Perspectives, edited by Jae Hee Han and Annette Yoshiko Reed</issue-title>
Add the <issue-title>-element after the <issue>-element with the number of the issue.
