<object-id>

Object Identifier

Used to record an identifier, such as a DOI, for elements other than the top-level element <article>

Remarks

Such an identifier may be created by a publisher or archive, and there is no requirement that identifiers be unique.

Design Note: An element, rather than an attribute, was chosen as the means to capture DOIs and other identifiers so multiple identifiers could be retained.
