Multiple subtitle lines may occur in a publication. Although the JATS and BITS standards allow multiple subtitle elements to be used, the use of more than one subtitle line raises problems in the registration of title information together with the DOI at Crossref. Also, at brill.com only the first subtitle element is being displayed.  To avoid this, multiple subtitle lines should be combined in one <subtitle>-element. A <break/>-instruction can be used to start a 2^nd subtitle line on a new line.

If used, a <trans-title-group> should also contain only one <trans-subtitle>-element. If necessary, the <break/>-instruction can also be used here.
