<object-id>

Object Identifier

Unique identifier (such as a DOI or URI) for a component within an article (for example, for a figure or a table).

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.
