<object-id>

Object Identifier

Unique identifier (such as a DOI or URI) for a component within a document such as a standard or a journal article (for example, for a figure, table, or text box within a standard).

Remarks

These identifiers may be created by a standards organization, publisher, or archive, and there is no requirement that identifiers be unique.
Design Note: Particularly in citations, an <object-id> is used to identify parts of a document, for example, a particular section, a figure, a table, or even a specific citation (as an entity) in the document’s reference list. The <pub-id> element may be used inside a citation to identify a cited publication.
