Container element for the parts of a single date associated with an article’s publication (for example, date preprint was released, date article was published in print).
As part of the article metadata (<article-meta>), the element <pub-date> is allowed to repeat; each repetition can take a different @publication-format attribute to distinguish which form of publication, for example, print publication, electronic publication, etc. and a @date-type attribute to distinguish between preprint, publication, revision received, etc.
