The abstract is a summary of the contents of a paper, and is typically made available via search services to give potential readers a flavor of the content of the article.
eXtyles supports both Teasers (very short summaries, typically a single sentence) and longer Abstracts that may contain several paragraphs.
Abstract Head
Abstracts do not require titles in the XML according to the JATS DTD, but, if a title is provided, it should be styled as Abstract Head.
Abstract
Each paragraph of the body of the abstract should be styled as Abstract.
If the abstract contains headings (e.g. Introduction, Methods, Results, etc.), these should be run in to the text of the paragraph and distinguished by the use of bold face.
