xlink:href

Href (XLink Linking Mechanism)

An address or identifier that permits an XLink application to find a remote resource, for example, a URI (such as a URL or filename) that links to an online site associated with the author or the online definition of a term. As specified in XML Linking Language (XLink) Version 1.0, the value of an @xlink:href must be a valid URI. (See https://www.w3.org/TR/xlink/)

Remarks

Of the many linking attributes that may be used, @xlink:href is the most important, since it provides the link. The attribute is required for those elements which must link, and it is optional on other elements only in the sense that an element need not link. If an element links, this attribute is required.

Used on Elements: <graphic>, <inline-graphic>, <media>
