Description of the Element

extptr = External Pointer. An empty linking element which connects the gazetteer to an external (most often, binary) electronic object, such as an image. It is a semantic error not to have either an entityref or href attribute.

Attributes of the Element

The href attribute is provided as a substitute for entityref's actual URI for those systems incapable of handling entityrefs.

The xpointer attribute is for specifying the target using CDATA, e.g. an XPath expression.
