The subordinate name of a journal component such as an article
Conversion Note: This may be a rarely used metadata element within the journal metadata, as many journal Tag Sets choose not to recognize subtitles, placing both the title and the subtitle information into the article title element (<article-title>).
Conversion Note: Within a bibliographic reference element (<citation> or <nlm-citation>), the subtitle is never tagged and must be subsumed within another title element. A subtitle in a citation should become part of the Article Title <article-title> element or the Source <source> element, which is used for book titles, proceedings title, and other titles.
