- | (blank) / primary - There is no default value. The first abstract in the article is normally the abstract used for display on the article's online abstract page and for indexing. The value "primary" may be used to explicitly indicate the same. |
- | graphical - Graphical abstracts contain only images, possibly with captions, and are sometimes included in addition to an articles' primary abstract or as the articles' only abstract. Though not restricted by the DTD, graphical abstracts should contain only a <title> (which is optional) and <figure> elements. |
