<std-id> Standard ID

One identifier (such as a DOI, URN, standard designator, or standards organization’s internal document ID) for a standard, using the @std-relationship-type attribute to name the type of identifier (such as dated or undated designations).

Usage/Remarks

Several <std-id> identifiers may be grouped into a container element <std-id-group> to indicate that they are alternative identifiers for the same standard. For example, such a group could contain: one <std-id> containing a DOI, a second <std-id> containing a URN, and a third containing a standards-producing organization’s internal-processing identifier. Thus each <std-id> (with its attributes) can be used inside the <std-id-group> element to support the coupling of identifiers, such as the designator and the URN, and to describe this relationship.
