Subtitle. In the article metadata, the article subtitle and title are identified with two different elements and tagged separately, using the <article-title> and <subtitle> elements.

Best Practice. Although this Tag Set cannot enforce either practice, retrieval performance will be enhanced if the subtitle is consistently placed within the <article-title> element (or the <source> element for book titles, proceedings titles, and other titles) for all cited material. Either with a <named-content> or as untagged text, the subtitle is easy to lose to searching. It is also not always obvious, particularly with historical or foreign material, which part of a multipart title is the main title and which the subtitle.
