<std-xref> Cross-Reference to a Standard

Used within one of the standards metadata elements to identify, and possibly provide a link to, another standard. This element is used to name a related standard, for example, a standard that has been revised, amended, or replaced by the current standard.


Relationship to Standard Citation

The <std-xref> element is part of the metadata of a standards document, where it is used to mention and/or point to a related standard, for example, a standard that this standards document amends. In contrast, when a standard is mentioned within the prose of a standards document, the element <std> holds the designation and other information for the standard being cited. Inside the <std> citation, the element <std-ref> may be used to identify the designation of the cited standard and separate it from other information concerning the standard.
The @type attribute can be used to indicate the relationship between the current standards document and the standard being referenced. For example, the value “amends” indicates that this is a reference to the standard which the current document amends, and the value “revises” indicates that the reference is to the standard which the current document revises.
The typical <std-xref> element contains just the designator of the standard (tagged as a <std-ref>) and an attribute to explain the relationship to the standard being mentioned. To tag a full citation to a standard, Best Practice is to use the <std> element.
