I would like to describe irregular volume/issue titles such as ‘xx anniversary issue (○○記念号)’ or ‘xx special issue (○○特集号)’ but I cannot find an item like ‘issue.alternative’. Where should I describe them?

Please describe them in ‘descriptionType attribute＝“other”’ in ‘10. Descriptions (datacite:description)’.
