Note

The value may be a unique identifier from a database, or any other externally-defined string identifying the referent.

No particular syntax is proposed for the values of the key attribute, since its form will depend entirely on practice within a given project. For the same reason, this attribute is not recommended in data interchange, since there is no way of ensuring that the values used by one project are distinct from those used by another. In such a situation, a preferable approach for magic tokens which follows standard practice on the Web is to use a ref attribute whose value is a tag URI as defined in RFC 4151.

ref(reference) provides an explicit means of locating a full definition or identity for the entity being named by means of one or more URIs.
Status Optional
Datatype 1–∞ occurrences of teidata.pointer separated by whitespace
<name ref="http://viaf.org/viaf/109557338"
 type="person">Seamus Heaney</name>
Note

The value must point directly to one or more XML elements or other resources by means of one or more URIs, separated by whitespace. If more than one is supplied the implication is that the name identifies several distinct entities.
